Question

Question:
An air spring is used to protect a support and prevent damage to a tensioning weight in the event of a belt failure. The force developed by the air spring as a function of its deflection is linear: the force increases from 0 Newtons at s equals 0 meters, to 1500 Newtons at s equals 0.2 meters. A block of mass 20 kilograms is suspended a height d equals 0.4 meters above the top of the undeformed spring. Determine the maximum deformation s-max of the spring when the belt fails. Neglect the mass of the pulley and belt.

Problem 14-9: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

This lesson applies the work-energy theorem to find the maximum compression of a linear air spring that catches a falling mass after a sudden load release. Students integrate a linearly varying spring force and solve the resulting quadratic equation to determine the maximum deflection, verifying
