5. (15 points) As shown in Figure 4, A homogenous rod with a fixed left end and a spring connected to the right end. Rod parameters: the length is 1. cross section area is A, material density is p, elastic modulus is E. and the stiffness of the spring is k, Where E, A, p and m are units 1, and /= ID which is your class number. (1)Try to derive the differential equation of longitudinal motion and give the boundary conditions; (2)Try to derive the frequency equation of the system, when the stiffness k=0; (3)Try to gain the natural frequency and modal function respectively, when the stiffness ko, 1 Fig.4 ww
