The coefficient of static friction μs between the 132-lb body and the 22° wedge is 0.37. Determine the magnitude of the force P required to begin raising the 132-lb body if (a) rollers of negligible friction are present under the wedge, as illustrated, and (b) the rollers are removed and the coefficient of static friction μs = 0.37 applies at this surface as well. Answers: (a) P = (b) P = 22° 132 lb i lb i lb
