The coefficient of static friction u, between the 130-lb body and the 16 wedge is 0.21. Determine the magnitude of the force P required to begin raising the 130-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 u, = 0.21 applies at this surface as well. 130 lb 16
