Question
The coefficient of static friction between the drum and brake bar is μs = 0.4. If the moment M = 35 N ⋅ m, determine the smallest force P that needs to be applied to the brake bar in order to prevent the drum from rotating.
Also determine the corresponding horizontal and vertical components of reaction at pin O. Neglect the weight and thickness of the brake bar. The drum has a mass of 25 kg.
