A rod is bent into an L shape and attached at one point to a plvot. (Figure 1The rod sits on a frictionless tabie and the diegram isa view trom above. This means that gravity can be ignored for this problem. There are three • Part A If F = 0 arnd Fi = 12 N, what does the magritude of Fa have io be for there lo be ralalional equilibriurn? forces that are apolied to the rod at cifferent points and angles: F1, F's, and F1. Note that the dimensions of the bent rod are In centimeters in the figure. athough the answers ere requested in Sl units (klograms, meters, seconds).
