Question:
The 100-lb block D is supported as shown by three springs, each of which has a constant k. The period of vertical vibration is to remain unchanged when the block is replaced by a 120-lb block, spring A is replaced by a spring of constant kA, and the other two springs are unchanged. Knowing that the period of vibration is 0.4s determine the values of k and kA.
