Two blocks A and B, each having a mass of 7 kg , are connected by pins using the linkages shown. B 02 The coefficient of static friction between Block A and the floor is µ, = 0.2. The coefficient of static friction between Block B and the floor is µR = 0.41. The angles given are O1 = 45 degrees 02 = 25 degrees Neglect the weight of the links. i. Draw the Free Body Diagrams for pin C, Block A, and Block B. ii. Applied force P on pin C is gradually raised. Which block starts slipping first and what is the value of P when slippage starts occurring? Hint: It helps to establish two cases, one in which block A slips and one in which block B slips, and then calculate what occurs in each case in order to determine what happens.
