1. Determine the fundamental frequency of a uniform fixed-fixed beam carrying a mass M at the middle by applying Rayleigh’s method. Use the static deflection curve for W(x).

2. Applying Rayleigh’s method, determine the fundamental frequency of a cantilever beam (fixed at x = l) whose cross-sectional area A(x) and moment of inertia I(x) vary as A(x) = A_{0}x/l and I(x) = I_{0}x/l.
