Extracted text: Q1:- The 35-kg block shown in figure below is held against the wall by the brake arm. The coefficient of friction between the wall and the block is 0.22; and between the block and the brake arm is 0.45. Neglect the weight of the brake arm. 1. Determine if the system would be held in equilibrium if P = 250 N. 2. Determine the minimum and maximum force P for which the system would be in equilibrium. 125 N 35 kg 50 mm 35 mm
