Finding tensions from incline

[QUOTE="haruspex, post: 4945723, member: 334404"] You won't need to consider the coefficient of friction to answer this part. Do you understand how to develop free body diagrams when there are multiple interacting bodies? You create unknowns for all of the forces of interaction (the tensions here), draw a free body diagram for each body, and write down the dynamical equations for each body. You also need to make use of kinematic facts, like the fact that some string length does not change. This allows you to deduce that some velocities or accelerations are the same. Where a body has no mass (the pulley here) you know the sum of the forces and sum of torques are zero. [/QUOTE]
