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, F? 2, and F? 3. Note that the dimensions of the bent rod are in centimeters in the figure, although the answers are requested in Sl units (kilograms, meters, seconds). If F3=0 and F1=12N, what does the magnitude of F? 2 have to be for there to be rotational equilibrium? Answer numerically in newtons to two significant figures. 3 cm Pivot 8 cm 16 F₁ 30° A rod is bent into an L shape and attached at one point to a pivot.
