Question
The horizontal force P = 50 N is applied to the
upper block with the system initially stationary.
The block masses are ma = 10 kg and mg = 5 kg.
Determine if and where slippage occurs for the fol-
lowing conditions on the coefficients of static fric-
tion: (a) µ = 0.40, µ2 = 0.50 and (b) µz = 0.30, µ2 =
0.60. Assume that the coefficients of kinetic friction
%3D
are 75 percent of the static values.
