Solve all problems using the finite element stiffness method.

Determine the free-end deflection for the tapered beam shown in Figure P4–46. Here I (x) = I₀(1 + nx=L) where I₀ is the moment of inertia at x = 0. Compare the exact beam theory solution with a two-element finite element solution for n = 7[12].
