Question

Problem 2 The system shown is in equilibrium. The mass m = 15 kg for all questions. For all questions, assume no mechanical interference of the spring or cables with the supports, and neglect any friction and pulley mas. What should the mass of the cart on the incline be if the stretch in the spring is 250 mm? The spring stiffness is k = 125 N/m. If the mass of the cart on the incline is 15 kg, what is the resulting stretch, or compression, in the spring? 1. 2. Cart k 125 N/m
