Figure shows a 100 kg concrete cylinder resting on a wall at A. A 10° wedge is used at the bottom to prevent the concrete cylinder from rolling. The coefficients of static friction at A and B are 0.6 and 0.2, and the coefficient of static friction between the wedge and the floor is 0.3. By assuming the negligible weight of the wedge, determine the force P required to lift the concrete cylinder in the direction shown.
