Question: A fixed-end beam of length L is loaded by distributed load in the form of a cosine curve with maximum intensity q0 at A. (a)

A fixed-end beam of length L is loaded by distributed load in the form of a cosine curve with maximum intensity q0 at A.
(a) Use the fourth-order differential equation of the deflection curve to solve for reactions at A and B and also the equation of the deflection curve.
(b) Repeat (a) using the distributed load q0 sin (Ï€x/L)
