The light rod is pivoted at O and carries the 8- and 10-lb particles. If the rod is released from rest at θ = 30° and swings in the vertical plane, calculate 

(a) The velocity v of the 8-lb particle just before it hits the spring 

(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.
