Blocks A and B have masses of 10 kg and 20 kg respectively. The coefficient of static friction between A and B is 0.20, between B and C is 0.10 and at D, 0.15. Block B impends to slide up the 30°- incline plane. (A) Draw the FBD of block A (B) Draw the FBD of block B (C) What is the weight of the hanging block that will maintain static equilibrium? Note: Use T, and T2 for tension on the tight side and slack side of the cord respectively.
