Problem # $5$:

Neglect the self$-$weight of the beam shown below. The magnitudes of the reactions have been provided:

At pin $A,$ the vertical reaction is $360$ lbs At pin $A,$ the horizontal reaction is $0$ lbs At roller $B,$ the vertical reaction is $540$ lbs

$120lb\frac{s}{f}t$

$($a$)$ Determine the internal shear force as a function of $x$ along the length of the beam.

$(10$ pts$)$

$($b$)$ Determine the internal moment as a function of $x$ along the length of the beam.

$(10$ pts$)$

$($c$)$ Plot the shear and bending moment diagrams.
