In the last two integrations, the number of grid points at which an exact integral can be calculated is halved as a result of using Simpson's rule. Using Simpson's rule is required because we are integrating a higher-order function. The trapezoid rule is sufficient for the first two integrations because it can still produce exact numerical integrals of zero- and first-order functions. This also means that the applied load on the beam must be evaluated at more grid points than will be present in the final result for ybar.

To perform the numerical integration and calculation of $\overline{V}$, $\overline{M}$, $\overline{\theta}$, and $\overline{y}$, we use the trapezoid rule and Simpson's rule, discretizing the functions on a grid of points between 0 and $L$. We also add a grid point at each point load or anchor. During the integration, point loads can create discontinuities. In these cases, two grid points are created with the same x-coordinate, and each is assigned to one side of the discontinuity.

The prominence of DSLRs in the market is rooted in their history and their adaptability. They offer a wide range of interchangeable lenses, from wide-angle to telephoto, giving photographers the flexibility to shoot in a variety of situations. High-quality image sensors and fast autofocus systems also make DSLRs well-suited for action photography and low-light conditions. However, as the technology has matured, the industry has begun to shift toward the more compact mirrorless cameras. Despite this, DSLRs continue to be a reliable choice for many photographers, owing to their robust build, battery longevity, and the extensive range of available lenses and accessories. In fact, many professional photographers still prefer to shoot with workhorse DSLRs like the Canon EOS-1D X Mark III or the Nikon D6.

One of the most significant advancements in smartphone photography has been the integration of Artificial Intelligence (AI). Through computational photography, AI algorithms enhance image quality in real-time, often matching and sometimes even exceeding the capabilities of traditional cameras. Features like portrait mode, Night Sight, and Smart HDR rely on AI to analyse and adjust settings instantaneously, making it easier for users to capture professional-quality photos without the need for manual adjustments. These advancements have democratised photography, allowing virtually anyone with a smartphone to become an amateur photographer capable of producing high-quality images.

Any number of joints can be added in this way, and the degrees of freedom remain unchanged. In practice, only fixed joints on the ends of beams are allowed, because a fixed joint in the middle of a beam would divide it into two independent beams, each having a fixed joint on one end.

Smartphone cameras have become an indispensable tool in modern photography, offering unparalleled convenience and portability. While they may not replace specialised equipment for professional use, the capabilities of smartphone cameras have advanced dramatically over the years. Today’s high-end models, like the iPhone 15 Pro or the Google Pixel 8 Pro, come equipped with multiple lenses, impressive low-light performance and in some cases even LiDAR technology for improved depth sensing.

The development and adoption of mirrorless technology has marked a significant shift in photography. While DSLRs have been the go-to choice for professionals for many years since digital photography became the norm, the technological advancements in mirrorless cameras have made them equally – if not more – capable in terms of image quality, autofocus and versatility. The absence of a mirror allows for faster shooting speeds, quieter operation and the ability to incorporate advanced features like in-body image stabilisation. They have become particularly popular among both hobbyists and professionals who are looking for high-quality performance in a more portable package.

Digital Single-Lens Reflex (DSLR) cameras have long been the standard for both amateur photographers and professionals alike. A DSLR employs a mirror mechanism to direct light from the lens up into an optical viewfinder, allowing you to see exactly what the lens sees. This is different from mirrorless cameras, which provide a digital preview directly from the image sensor. Popular DSLR models include the Canon EOS series, Nikon D series and the Pentax K-series.

Best Scenarios for UseSuitable for professional photography, fine art and any scenario where high-quality images are a must.

Point-and-shoot cameras are compact, convenient, and designed for simplicity. They typically come with a fixed lens, meaning you can’t change it out for a different one. These cameras automatically adjust settings like focus, exposure and shutter speed, taking much of the guesswork out of photography, freeing you to simply be in the moment and concentrate on composition and capturing the scene. Advanced point-and-shoot cameras, like the Sony RX100 series, tend to offer some level of manual control, along with features like optical zoom and image stabilisation.

The shear force at $x = x_1$ and $x = x_2$ is undefined due to the discontinuities at these points, but this doesn't matter since calculating the integral across a discontinuity is trivial.

Mirrorless cameras have gained significant traction over the last decade, posing a serious challenge to the longstanding reign of DSLRs. Unlike DSLRs, which use a mirror mechanism to reflect light into an optical viewfinder, mirrorless cameras eliminate the need for a mirror altogether. This results in a more compact and lightweight design. The image sensor is exposed to light directly, providing a digital preview of the image either on the camera’s rear screen or through an electronic viewfinder. Popular examples of mirrorless cameras include the Sony Alpha series, Canon EOS R series, Nikon Z range of cameras and the Fujifilm X series.

The base set of equations is obtained by considering an unsupported beam. At each end of the beam, the shear force and moment are both zero, since there are no applied moments or forces. For this trivial problem, we have 4 unknowns (the 4 constants of integration) and 4 equations: $V(0) = 0$, $M(0) = 0$, $V(L) = 0$, and $M(L) = 0$.

$$ M(x) = \begin{cases} \overline{M}(x) & x = 0 \\ \overline{M}(x) - p_0 x + m_0 & 0 < x < x_1 \\ \overline{M}(x) - p_0 x - p_1 (x - x_1) + m_0 & x_1 < x < x_2 \\ \overline{M}(x) - p_0 x - p_1 (x - x_1) - p_2 (x - x_2) + m_0 & x_2 < x < L \\ \overline{M}(x) - p_0 x - p_1 (x - x_1) - p_2 (x - x_2) + m_0 + m_L & x = L \end{cases} $$

We've taken a bit of a leap here moving from five to three piecewise portions, which one can confirm by working out the various pieces, or simply come to accept by recognizing that $\theta$ must be continuous.

Firstly I used a Canon Powershot SX730HS and i was Canon itself who suggested to me the best type of camera to buy a few years ago: a Canon DSLR 200d and two different lenses – EF 55-250mm IS and an EF Macro 100mm 1:2.8 IS USM, to which I added an extension tube EF 12 II. Afterwards, I bought a TAMRON lens 18-400 mm f/3.5/6.3 . However, on a dayly basis, I still prefer the portable Powershot for quick/unexpected situations, although I recognize that the images quality is not the best. But I have to also inform that I’m a 75 years old woman and regrettably cannot carry many/heavy equipment or even go walking in rough soil, etc. That’s when I “discovered” a passion for macro photography.

Drones with cameras, such as the DJI Mavic series, are excellent for capturing aerial photographs and video. Drones are ideal for landscape photography, photographing real estate and surveying large areas.

Best Scenarios for UseExcellent for social media, casual photography, and even some niche professional applications like street photography.

Because the constants of integration and anchor forces and moments are unknown, we have to carry them symbolically through the integration. In practice, we begin by first numerically integrating only the known loads on the beam, and add the unknown forces after the integration. We will use an overbar to show that we have ignored the unknown constants of integration and anchor loads and moments:

This is because the camera you use becomes an extension of your vision. From the casual shutterbug to the aspiring professional, choosing the right camera is a crucial first step.

The final step is to solve for the remaining unknown variables $c_3$, $c_4$, and others introduced by the various anchors. The remaining boundary conditions not yet considered are $V(L) = 0$ and $M(L) = 0$. Each pin joint adds one unknown $p_i$ and one equation $y(i) = 0$, and each fixed joint adds the unknowns $p_i$ and $m_i$, and the equations $\theta(i) = 0$ and $y(i) = 0$. Thus, the degrees of freedom for the problem is always zero. This is a straightforward linear algebra problem that can be solved with a method such as LU-decomposition. The difficulty lies in preparing the matrix and keeping all our ducks in a row.

We have now worked out the expression for the fully generalized beam. Adding additional pinned joints just increases the number of piecewise portions.

We won't know a priori if the applied load is a constant or not--the user simply provides a function. We think the method of integration above will provide sufficient accuracy for non-uniform loads, and has the benefit of providing exact answers for uniform loads.

Now say we add a pinned joint $p1$ at some location $x1$ on the beam. This introduces one additional unknown, $p1$, the force applied on the beam by the joint. It also introduces another equation: $y(x1) = 0$. There are still zero degrees of freedom:

Each step introduces an unknown constant of integration. These unknowns are solved for based on the constraints applied to the beam, such as the presence of pinned or fixed anchors. Other unknowns, such as reaction forces from anchors, are solved for in the same way.

At this point, we recognize that the constants $c_1$ and $c_2$ must both be equal to zero in order to satisfy our first two base equations, $V(0) = 0$ and $M(0) = 0$. We also make a few other simplifications:

At the present time, the implementation requires the beam to have constant rigidity $EI$. This is so that unknowns which appear in intermediate integrations can be carried through symbolically, and all solved simultaneously at the end.

Instant cameras, such as the Fujifilm Instax series, offer immediate gratification by printing photos on the spot. They’re great for social events and scrapbooking, offering a tangible memento that digital photos can’t provide.

For a beam of constant rigidity $EI$, the Euler-Bernoulli equation describes the relationship between the deflection of the beam and the applied load:

Traditionally, different approaches are taken to solve a beam deflection problem depending on the particular anchors present. However, in order to simplify the implementation, we have considered all beams to be free-floating with the same set of boundary conditions. This establishes a base set of equations and unknowns with zero degrees of freedom. Then, each anchor adds either one or two additional equations and unknowns in a predictable way. This allows us to use one implementation to solve any configuration of anchors.

Likewise, adding a fixed joint to the end of the beam does not alter the original $M(0) = 0$ boundary condition, since an applied moment causes a discontinuity in $M$, and the boundary still holds on one side of the discontinuity.

Action cameras are small, portable, and often rugged devices designed to capture high-quality video and stills in a variety of dynamic environments. Unlike traditional cameras, action cameras are built to be highly durable, water-resistant, and often shockproof. These cameras are intended for capturing fast-paced activities, whether it’s mountain biking, skydiving, or scuba diving. GoPro, with its HERO Black series, has long been the most popular action camera around. There have been lots of other competitors over the years, but none of them have matched GoPro for features and quality. The only brand that’s come closest is DJI, with its Osmo Action range.

If we add a fixed joint to the left end of the beam, we add two additional unknowns and equations. The unknowns are $p0$ and $m0$, and the equations are $y(0) = 0$ and $\theta(0) = 0$:

Photography is more than just the click of a shutter; it’s a way to freeze time, capture memories and communicate visually. And as we spend more of our time online, capturing these moments has become an integral part of our lives. Whether you’re a seasoned professional or someone who’s just starting to dip their toes into photography, the camera you choose can make all the difference. But with an array of options available – ranging from classic film cameras to advanced mirrorless cameras and even smartphones with AI-powered lenses – the task of choosing the right camera can be overwhelming, to say the least.

The numerical integration to find $ybar$ is only half the battle. To fully solve the problem and find the as yet unknown constants of integration, consider this generalized example. Assume that we have a fixed anchor on the left with reaction force $p_0$ and moment $m_0$, a fixed anchor on the right with reaction force $p_L$ and moment $m_L$, and two pinned joints located at $x_1$ and $x_2$, with unknown reaction forces $p_1$ and $p_2$. The presence of anchors means that the integration is carried out piecewise. The shear force $V$ is then given by:

$$ M(x) = \begin{cases} \overline{M}(x) + c_1 x + c_2 & x = 0 \\ \overline{M}(x) + c_1 x + c_2 - p_0 x + m_0 & 0 < x < x_1 \\ \overline{M}(x) + c_1 x + c_2 - p_0 x - p_1 (x - x_1) + m_0 & x_1 < x < x_2 \\ \overline{M}(x) + c_1 x + c_2 - p_0 x - p_1 (x - x_1) - p_2 (x - x_2) + m_0 & x_2 < x < L \\ \overline{M}(x) + c_1 x + c_2 - p_0 x - p_1 (x - x_1) - p_2 (x - x_2) - p_L (x - L) + m_0 + m_L & x = L \end{cases} $$

Adding a pinned joint to the end of the beam does not alter our original $V(0) = 0$ boundary conditions, so long as we account for the fact that a point load causes a discontinuity in $V$, and that on one side of the discontinuity, the boundary condition will still hold.

Whenever possible, we would like the numerical integration to be as accurate as possible. It turns out that if the applied load to the beam, $w(x)$, is either uniform or a point load, we can carry out each numerical integration exactly. Here's why:

These cameras capture a 360-degree field of view, offering the viewer an immersive experience. The GoPro MAX and the Insta360 One X are popular examples of this type of camera, and you can even spend thousands and buy professional 360 cameras. These types of cameras are ideal for virtual tours, adventure photography or capturing large scenes in a single shot.

History and Market PositionEmerging as a serious competitor to DSLRs in the last decade, mirrorless cameras are increasingly the choice for professionals and amateurs alike due to their blend of size and performance.

Whether you’re a novice looking to get started or a seasoned photographer considering an upgrade, read on to gain valuable insights that will help you make an informed choice.

The rise of action cameras has had a significant impact on how we capture and share experiences. They have enabled adventurers, athletes, and vloggers to easily record footage from unique perspectives, thanks to their small size and mounting capabilities. While they may lack the image quality and versatility of more traditional camera types, action cameras excel in situations that require durability and portability. In addition to their robust build, these cameras usually offer a wide-angle field of view to capture as much of the action as possible, along with features like image stabilisation, slow-motion capture, and easy integration with mobile apps for on-the-go editing.

History and Market PositionOnce the go-to for casual photographers, point-and-shoot cameras have somewhat fallen out of favour due to the rise of smartphones, which have all but eaten away their share of the market. However, point-and-shoot cameras still find a niche among those who want something better than a phone but simpler than a mirrorless camera.
