Question

3 A tall block of uniform mass density is resting on an initially horizontal surface, and the inclination of the surface, described by the angle e, is steadily increased. The block weighs 200 N, and it is 600 mm high, and 250 mm wide. The coefficients of friction between the block and the surface are us = 0.5 and uk = 0.4. What will happen when the inclination angle is gradually increased? (15 Puan) 250 600 H, -0.5 Ik -0.4 slips at 22.62° slips at 26.56° slips at 21.8° tips at 26.56° tips at 22.62
