1. Two heavy boxes, on and 1112, lie stationary on different inclines, as shown. A rope runs over a pulley and connects the boxes. Mass 1, m1 is 330 kg. Assuming that each incline is frictionless and the system is in equilibrium, answer the following: a) Draw FBD(s). [2 marks] b) Find the magnitude of the tension in the cable. [3 marks] c) Calculate the mass of m: needed to keep the system in equilibrium. [3 marks]
