Given: The fixed$-$end cantilever beam shown below. $(25$ pts$)$

Find: a$)$ Find $A_y,M_A$ & write the equation for shear, $V(x),$

b$)$ Write the equation for moment, $M(x),$

c$)$ Use the double integration method $(y^{\text{'}\text{'}}=\frac{M}{E}$I $)$ to find $y^{\text{'}}(x)$ and $y_{\text{m}\text{a}\text{x}}^{\text{'}}$ in radians,

d$)$ Use the double integration method
