An object is hanging by a string from the ceiling of an elevator. The elevator is moving upward with a constant speed. What is the magnitude of the tension in the string? The magnitude of the tension in the string is equal to the magnitude of the weight of the object. The magnitude of the tension in the string is less than the magnitude of the weight of the object. The tension in the string cannot be determined without knowing...

A chandelier with mass m is suspended from a cable with mass M from the ceiling. Take a Y-axis vertically up and apply Newton's 2nd law to find the magnitude of the tension at the top and at the bottom of the rope. Treat the weight w of the chandelier and the weight of the cable W as given. Draw a free body diagram for both the rope and the chandelier.

As shown, a frictionless pulley hangs from a system of
springs and a cable. The pulley is equidistant between the two
supports attaching the springs to the ceiling. The distance between
the supports is d=1.50 m . The cable cannot stretch and its length
between the two springs is 1.8 m.
