Question: A 2 0 0 lb block rests on a horizontal surface. A friction wedge with an angle of = 1 5 theta = 1

A 200 lb block rests on a horizontal surface. A friction wedge with an angle of =15\theta =15^\circ=15 is used to lift the block by applying a horizontal force PPP. The coefficient of static friction is s=0.25\mu_s =0.25s=0.25 for all contact surfaces.
