. Consider the cantilevered beam with an intermediate spring of stiffness constant k, subjected to a uniform transverse load po, as depicted in fig. 3. Let a = a/L, P. and k = kl/Hz. (1) Use the principle of super- position to find the solution for this problem. (2) Describe the solutions that you will be superposing k clearly. (3) What condition will you use to find the force in the spring? (4) Find the force in the spring. L (5) Find the transverse deflection of the beam.
