$7\mathrm{.}87$ and $7\mathrm{.}88$ For the beam and loading shown, $($a$)$ write the equations

of the shear and bending$-$moment curves, $($b$)$ determine the magni$-$

tude and location of the maximum bending moment.

for $7\mathrm{.}87$ ONLY please

Find Ax and Ay first, then create the mending moment graph and the sheer moment graph using the sum of the forces in Fy and the moment about some point x which is between $0$ to L$.$
