Engineering Mechanics - Dynamics Chapter 14 Problem 14-31 The collar has mass M and slides along the smooth rod. Two springs are attached to it and the ends of the rod as shown. If each spring has an uncompressed length L and the collar has speed v 0 when s = 0, determine the maximum compression of each spring due to the back-and-forth (oscillating) motion of the collar. Given: M 20 kg = a 0.25 m = L 1m = k A 50 N m = v 0 2 m s = k B 100 N m = Solution: 1 2 Mv 0 2 1 2 k A k B + () d 2 0 = d M k A k B + v 0 = d 0.73 m = * Problem 14-32 The cyclist travels to point A , pedaling until he reaches speed v A . He then coasts freely up the curved
