Question:
A 4.08-kg block is supported as shown by three springs, each of which has a constant k. In the equilibrium position the tensions in springs A, B, and C are 12N, 16N, and 12N, respectively. The block is moved vertically downward 12.5mm from its equilibrium position and released from rest. Knowing that in the resulting motion the minimum tension in spring B is zero, determine
(a) The spring constant k,
(b) The frequency of the motion,
(c) The maximum compression in spring A.
