Question

A rod is bent into an L shape and attached at one point to a pivot. (Figure 1) The rod sits on a frictionless table and the diagram is a view from above. This means that gravity can be ignored for this problem. There are three forces that are applied to the rod at different points and angles: F_1_vec, F_2_vec, and F_3_vec. Note that the dimensions of the bent rod are in centimeters in the figure, although the answers are requested in SI units (kilograms, meters, seconds).

Assume that as the object starts to move, each force moves with the object so as to retain its initial angle relative to the object.

Explanation / Answer

T1= T2 for equilibrium r x F1 = r x F2 (.03m)(12) = (.08m)(F2) F2 = 4.5 N
