Question

A flat-screen monitor is mounted on the wall inside an elevator with four steel bolts, each with a diameter of 0.500 cm. A gap of 15.0 cm is left between wall and monitor for air circulation. The mass of the monitor is 25.0 kg. You may assume that the weight is evenly distributed on the four bolts.

(1) Calculate the shear stress on each bolt when the elevator is at rest.
(2) Calculate the vertical deflection Δx of the bolts when the elevator is at rest.
(3) Calculate the vertical deflection Δx of the bolts when the elevator is accelerating upward at 3.00 m/s
