2. Find the first two natural frequencies and modes of a bar fixed at the right end and connected to a rigid wall by a spring at the left end as shown. The bar has length 1 = 2 m, density p= 195 kg/m>, cross-sectional area A=0.1 m², Young's modulus E = 2.05 MPa, and the stiffness of the spring is k= 488 kN/m. What happens to the natural frequencies as k is increased to infinity? WW WWWWWWWWWWW
