What is the formula for the 2 Point Load equation?

The formula for the 2 Point Load equation is utilized to determine the load distribution between two points on a beam or structure. The correct formulation considers the weight of the load (W), the distances from the points to the load (D2), and the overall span of the beam.

In the context of option A, the formula F1 = {(WxD2)} / Span accurately represents the principle of moments, which states that the moment about any point is equal to the sum of the moments created by individual forces acting on that structure. Here, W represents the total load being considered, D2 is the distance from the point of application of the load to the first support point, and Span is the total length between the two supporting points.

This formula allows for the calculation of the force F1 at one support when the load is located at a specific point (D2) along the span. This understanding of load distribution is critical in lifting and rigging applications to ensure that structures can handle the applied loads safely and effectively.

The other options do not provide the correct relationship needed to calculate the forces in a 2 Point Load scenario as accurately or directly, thus making option A the appropriate choice.
