Two successive amplitudes of a spring-block underdamped vibrating system are observed to be 100 mm and 75 mm. Determine the damping coefficient of the system. The block has a mass of 10 kg and the spring has a stiffness of k = 1000 N/m. Use the result of Prob. 22-55.

Prob. 22-55:

The motion of an underdamped system can be described by the graph in Fig. 20-16. Show that the relation between two successive peaks of vibration is given by is called the logarithmic decrement.
