What is the tilt angle load equation for a two-point load?

In a two-point load scenario, the tilt angle load equation helps determine the distribution of a total load (W) between two supports or points, referred to as F1 and F2. The correct expression is derived from understanding how the load is proportionally shared based on the distances from each point to the center span.

The equation F1 = (W)(D2/Span) effectively states that the force at point F1 is equal to the total load (W) multiplied by the ratio of the distance from the second point (D2) to the total span. This ratio reflects how the load is distributed; as the distance to the opposite point increases, more of the total load is carried by the nearer point.

Consequently, the correct answer relates to the fundamental principles of load distribution in a beam or rigging scenario, where distances influence how much weight each support must account for. Understanding this relationship is crucial for ensuring that load is managed safely in theatrical rigging applications.
