Problem $2(30$ pts$)$: Influence Lines in Determi$-$

nate Beams. For the beam shown below. Neglect the drawn loads for all other questions besides

$($b$).$

a$)$ Draw the influence line for the beam internal moment at A$.$

b$)$ What is the moment at A for the given external loads $($at the provided locations$)?$

c$)$ Draw the influence line for the beam$-$moment at B$.$

d$)$ Draw the influence line for the $($vertical$)$ reaction at B$.$

e$)$ Draw the influence line for the shear at K$.$
