Given: Find: A homogeneous block having a weight of Wis supported by a rough peg at B and a smooth roller support at C.. In the position shown, edges AC and CD of the block are horizontal and vertical, respectively. For this problem: a) Determine the required friction force on the block at B in order for the block to remain in equilibrium. Write your answer in terms of W. b) Determine the numerical value for the minimum #5 required to keep the block in equilibrium. "A $ \\\\ #3 C
