(b) Now consider the same bar with different boundary conditions as shown below. One end of the bar, say x = 0, is fixed. At the other end, x = L, the bar is attached to a massless linear elastic spring of constant / . Determine the frequency equation for this bar in terms of k, E, A, L and B. For k = EA/L, determine the lowest three (non-zero) circular frequencies of this system in term of E/pLZ. p, A, E, L 000 k
