Determine the natural frequency of the beam-spring system shown in Fig. 1.8 consisting of a weight of W = 50.0 lb attached to a horizontal cantilever beam through the coil spring k2.The cantilever beam has a thicknessh = 1/4 in a width b = 1 in. modulus of elasticity E = 30 x 10° psi, and length L = 12.5 in. The coil spring has a stiffness k2 = 100 (1b/in). L = 12.5 in- 1in 1/4in k2 = 1000 lb/in 50 lb
