Chapter 2, Problem 3E

Solve the differential equation in problem 2 using (a) two and (b) three finite elements. Use the finite element approximation described in section 2.4. Plot the exact solution and two- and three-element solutions on the same graph. Similarly, plot the derivative d u d x . Note: The boundary conditions are not homogeneous. The boundary condition u ( 0 ) = 1 has to be used in solving the final equations.

The 2-mass system shown below depicts a disk which rotates about its center and has rotational moment of inertia Jo and radius r. The angular displacement of the disk is given by 0. The spring with constant k₂ is attached to the disk at a distance from the center. The mass m has linear displacement & and is subject to an external force u. When the system is at equilibrium, the spring forces due to k₁ and k₂ are zero. Neglect gravity and aerodynamic drag in this problem. You may assume the small angle approximation which implies (i) that the springs and dampers remain in their horizontal / vertical configurations and (ii) that the linear displacement d of a point on the edge of the disk can be approximated by d≈re.
