12.22 To unload a bound stack of plywood from a truck, the driver first tilts the bed of the truck and then accelerates from rest. Knowing that the coefficients of friction between the bottom sheet of plywood and the bed are μ = 0.40 and μ = 0.30, determine (a) the smallest accelera- tion of the truck which will cause the stack of plywood to slide, (b) the acceleration of the truck which causes corner A of the stack to reach the end of the bed in 0.9 s.

Q2) A loaded Porter governor has four links each 200 mm long and are hinged at a distance of 40 mm from the axis of rotation. The mass of each ball is 2 kg and mass of the sleeve is 20 kg. The governor sleeve begins to rise at 300 r.p.m. when the links are at an angle of 35° to the vertical. Assuming the friction force to be constant, determine the minimum and maximum speed of rotation when the inc lination of the arms to the vertical is 40°.
