Question

A torsion pendulum with a vanadium wire containing nitrogen, and a period of 2.00 seconds, shows a decrease in the pendulum amplitude, A, of 10 percent in 100 cycles of oscillation at 350K. Compute:

a.The specific damping capacity.

b.The logarithmic decrement.

c. Tan α, where α is the phase angle by which the strain lags the stress.
