Plot the results of Prob. 1 in the permissible range.
Prob. 1
Using the result of Prob.2 , determine the amplitude of motion of a spring-rn ass system with Coulomb damping when excited by a harmonic force Fo sin wt. Under what condition can this motion be maintained?
Prob. 2
Coulomb damping between dry surfaces is a constant D always opposed to the motion. Determine the equivalent viscous damping.
