A pulley fixed to the ceiling of an elevator car carries a thread whose ends are attached to the loads of masses `3m` and `m` . The car starts gong up with acceleration `g//s`. Assuming the masses of the pulley and the thread, as well as friction, to be negligible, find the force exerted by the pulley on the ceiling of car.

A pulley fixed to the ceiling of an elevator car carries a thread whose ends are attached to the loads of masses m_1 and m_2 . The car starts going up with an acceleration w_o . Assuming the masses of the pulley and the thread, as well as the friction, to be negligible find: (a) the acceleration of the load m_1 relative to the elevator shaft and relative to the car, (b) the force exerted by the pulley on the ceiling of the car.
