Two heavy crates, m, and ma, lie on different inclines with angles 18.0 and 33.0, respectively (Figure 8). A cable, which runs over a pulley, connects the crates. The masses of the cable and the pulley are negligible. Assume that each incline is frictionless and that the system is in equilibrium. The mass of m, is 4.26 X 10' kg. (2.3) A M2 18.0 33.09 Figure 8 (a) Determine the tension in the cable. (b) Calculate the mass of m, needed to keep the system in a state of equilibrium
