Solving the pulley problem by writing the force equations by MIT OCW
Problem statement
Without writing the force equations, find the acceleration (a) of mass m in the pulley system shown in the figure. Reason the dependence of acceleration on the given masses m, M and acceleration due to gravity g by varying their values and comparing with known limits. Also, use the symmetries in the problem. Assume the pulley and rope to be massless and surfaces frictionless.
Similarly, find tension T in rope and A the acceleration of the center of mass of m and M.
