Laserbeamdiameter formula

Beam size refers to the cross-sectional dimensions of a beam that are required to support a given load over a span without exceeding the material’s allowable stress. The size is typically described by the beam’s height and width, which directly relate to the beam’s strength and ability to resist bending. Proper beam sizing is crucial in construction and engineering to ensure the safety and integrity of structures.

Beamdiameter calculator

Enter the load in pounds and the span in feet into the calculator to determine the required beam size in inches. This calculator assumes a uniformly distributed load and a rectangular beam cross-section.

To calculate the beam size, first calculate the maximum bending moment using the formula M = wL^2 / 8, where w is the load in pounds and L is the span in feet. Then, calculate the required beam height (h) using the formula h = (6 * M)^(1/3).
