Problem $2(9\mathrm{.}71$ in your textbook$)$

For the beam and loading shown, determine $($a$)$ the deflection at point $C,($b$)$ the slope at end $A_i$

Note: Use the method of superposition $($and Appendix $F$ in the textbook$)$ to solve this problem and assume that the flexural rigidity El$.$of the beam is constant.

$M_A=\frac{w{L}^2}{12}$
