Determine the maximum compression of spring HI if the fixed bumper R of a railroad car of mass M , rolling freely at speed v strikes the plate P . Bar AB slides along the guide paths CE and DF . The ends of all springs are attached to their respective members and are originally unstretched. Units Used: kN 10 3 N = Mg 10 3 kg = Given: M 5Mg = k 80 kN m = v 2 m s = k' 160 kN m = Solution: The springs stretch or compress an equal amount
