1. Consider the 2 dof of problem 1 in section 5 of the notes. (a) A time harmonic force f(t)= Feix acts on the left-hand mass. Find the modal forces and the responses of the modal coordinates y. (b) Find the physical responses x and find expressions for the receptances a11 and 21. Express these receptances clearly as the sum of two modal terms. (c) Find the receptances and a21 by directly inverting the matrix [K-w²M] and show that the result is identical to that which you found by modal decomposition.
