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.

In the pivoted motor mount shown, the weight W of the 175-lb motor is used to maintain tension in the drive belt. Knowing that the coefficient of static friction between the flat belt and drums A and B is 0.40 and neglecting the weight of platform CD , determine the largest couple that can be transmitted to drum B when the drive drum A is rotating clockwise.
Determine the maximum allowable value of weight W at rest. Knowing that the coefficient of static friction between the wall and the block 1 is 0.2, the coefficient of static friction between the floor and block 2 is 0.30 and the coefficient of static friction between the blocks is 0.15
A 10° wedge is used to split a section of a log. The coefficient of static friction between the wedge and the log is 0.35. Knowing that a force P with a magnitude of 600 lb was required to insert the wedge, determine the magnitude of the forces exerted on the wood by the wedge after insertion.

A 40-lb sliding panel is supported by rollers at B and C. A 25-lb counterweight A is attached to a cable as shown and, in cases a and c , is initially in contact with a vertical edge of the panel. Neglecting friction, determine in each case shown the acceleration of the panel and the tension in the cord immediately after the system is released from rest.
Required information A uniform thin bar AB of length L = 5.5 ft is released from rest at an angle 0 = 0₁. As the bar slides, the ends A and B maintain contact with the surfaces on which they slide.

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 inclination of the arms to the vertical is 40°.
