P04-07 The solid circular cylinder shown 50 kg. The cylinder rests on a block B which has a mass of 35 kg. When the force P 1s applied to the block, the block accelerates at a rate of 5 m/s^2. If the coefficients of friction between both the block and the cylinder and the block and the horizontal surface are 0.25, determine the magnitude of the force F and the frictional force exerted by the block on the cylinder.

Solution

Force F= umg( u=0.25, m=35kg, g=9.8m/s^{2). F= 0.25×35×9.8=85.75N.}
