The figure shows a part of a machine used to crush recycled cans. Link ABC is attached to the ground at pin A and link BD is attached to the piston D using also a pin connection. When α=45°, θ=55°, and β=15°, the machine is about to start moving, i.e. impending motion. If the coefficient of static friction and kinetic friction between the piston D and the wall are μs=0.25 and μk=0.2 respectively, find the magnitude of force applied to the cans by the piston for P=200 kN.
