Question

A 16~kg16 kg mass is attached to a spring. When the period of the free undamped motion of the system is \frac{4}{3}\pi~(sec) , find the stiffness of the spring.

A 16 kg mass is attached to a spring. When the period of the free undamped motion of the system is (sec), find the stiffness of the spring. 18 (kg/sec) 32 (kg/sec) 36 (kg/sec) 040 (kg/sec) 48 (kg/sec)

Answer 1

Answer: Stiffness is the extent to which an object resis ts deformation in response to an applied force. Time - period (T) = 2 and where, m = mass of the object affached to spring k = constant face for charasterstic of the spring lie, spring stiffness). Given, m = 16 kg T = 4 I (see) Also, I (spring stiffness k = mx 4 Top 16x.4709 1612 k=36 lkgl Sect),
