=+5. to observe the asymptotic behaviour of the solutions when ???? → 0 and when M → ∞.

Problem 4.3 The impedance matrix of a continuous bar was found in (4.167) as an expansion in terms of its fixed-fixed eigenmodes. It is also possible to compute the impedance matrix directly by considering the dynamic equation:

EAd2u dx2 + ω2mu = 0 (P4.3.a)
