A designer is trying to determine the type of wire to use for a pendant light that will hang from the ceiling of an elevator . The wire can withstand a force of 66 N before breaking. Therefore, the upward force on the lamp, called tension, cannot exceed 66 N. The lamp also experiences a 52-N gravitational force, called weight, in the downward direction. What is the maximum upward acceleration the elevator can have before the wire breaks? The lamp’s mass is 5.3 kg.
