Friction

B. C. uCG MAB HBC Three blocks are positioned on an incline of 0-27° as shown. A force of is applied to Block B and a wire attaches Block A to the wall, preventing that block from moving. The mass of Block A is ma=27kg, the mass of Block B is mg=59kg, and the mass of Block C is mc=40kg. The coefficient of static friction betwee Block A and Block B is uAB=0.28, between Block B and Block C is u BC=0.36, and between Block C and the ground is µcG=0.48. Determine the maximum value of P before any slipping takes place. Writ your answer for P in N units to 2 decimal places in the box below. Hint #1: Recall that the shear (tangential) force across a sliding surface c never exceed F = mu *N Hint #2: You will need to find a value for P based on the condition that one block slips AND a value for P based on the condition that multiple blocks slip. The final answer will be the lesser of the two values. Values: 0327° mA=27kg HAB3D0.28 mg359kg HBC%3D0.36 mc3D40kg HCG3D0.48
