In Prob. 11-10, determine the participation factor of the modes present and obtain a complete solution for an arbitrary time variation of the applied force.
Prob. 11-10
If the force of Prob. 11-9 is concentrated at x = l/3, determine which modes will be absent in the solution
Prob. 11-9
A siender rod of length I, free at x = 0 and fixed at x = I, is struck longitudinally by a time-varying force concentrated at the end x = 0. Show that all modes are equally excited (i.e., that the mode-participation factor is independent of the mode number), the compIete solution being
