Question: Rod AB is attached to a hinge at A and to two springs, each of constant k. If h = 700 mm, d = 300

Rod AB is attached to a hinge at A and to two springs, each of constant k. If h = 700 mm, d = 300 mm, and m = 20 kg, determine the value of k for which the period of small oscillations is

(a) 1 s,

(b) Infinite. Neglect the mass of the rod and assume that each spring can act in either tension or compression.
