The coefficients of static and kinetic friction between the drum and brake bar are μS= 0.4 and μK= 0.3, respectively. If M= 50 N.m and P= 85 N. determine the horizontal and vertical components of reaction at the pin O (shown in Fig. 3). Neglect the weight and thickness of the brake. The drum has a mass of 25 kg.
