Question

The desk has a weight of 54 lblb and a center of gravity at GG. The coefficients of static and kinetic friction at AA and BB are μsμs = 0.5 and μkμk = 0.2, respectively. (Figure 1)

Determine the initial acceleration of a desk when the man applies enough force FF to overcome the static friction at AA and BB.

Find the vertical reaction on each of the two legs at AA.
