Problem 69. The light rod is pivoted at O and carries the 8 lb and 10 lb particles. If the rod is released from rest at 0 = 30° and swings in the vertical plane, calculate (a) The velocity v of the 8lb particle just before it hits the spring and (b) The maximum compression x of the spring. Assume that x is small so that the position of the rod when the spring is compressed is essentially vertical. 18" 8 lb
