A force of P is applied to Block C and a wire attaches Block A to the wall, preventing that block from moving. The mass of Block A is mA=35kg, the mass of Block B is mg=49kg, and the mass of Block C is mc-54kg. The coefficient of static friction between Block A and Block B is HAB=0.19, between Block B and Block C is HBc=0.28, and between Block C and the ground is µcG=0.37. Determine the maximum value of P before any slipping takes place. Write your answer for P in N Hint #1: Recall that the shear (tangential) force across a sliding surface can never exceed F = mu * N ion that one block slips AND a value units to 2 decimal places in the box below. Hint #2: You will need to find a value for P based on the co for P based on the condition that multiple blocks slip. The final answer will be the lesser of the two values.
