Prob. $4\mathrm{.}3$c

d$.$ Derive the equations for the shear and moment for the original beam.

e$.$ Construct the shear and moment diagrams for the beam. Label values and

locations.

f$.$ Identify at least three features of the shear diagram that suggest you have

a reasonable answer.

g$.$ Identify at least three features of the moment diagram that suggest you

have a reasonable answer.

h$.$ Determine the peak moment due to the live load and its location.

i$.$ Make a comprehensive argument that the peak moment found in part $($h$)$

is reasonable.

j$.$ Comment on why your guess in part $($a$)$ was or was not close to the

solution in part $(h).$
