2. Consider a cantilevered beam with length L = 3 m, uniform E = 180 GPa, Iz- 5.375 × 10-8 m. and ρ 3.0 kg/m. (a) (20 points) Compute, by hand, the first 5 (lowest) natural frequencies for this beam. Note, unlike for the simply-supported beam problem, you will not be able to solve, analytically, the transcendental equation obtained from the application of the boundary conditions to the general free vibration solution. So, use Matlab roots of this equation numerically
