Problem #$2-$ Shear Force and Bending Moment Diagrams $(20$ points total, $3$ parts$).$

The simply supported beam with span length of $21-ft$ is loaded as shown below. A $4\mathrm{.}4\frac{k}{f}t$ uniformly distributed load acts across a $19-$ft section as shown, and a $52-$kip force acts downward at $19ft$ from point A$.$ Complete the following. Show all work and any assumptions clearly. Record your answers on the answer key:

Part $A(4$ points$)$: Calculate the support reactions at A and $B$ for the beam. Point $A$ is a pin support and point $B$ is a roller support.

Part B $(8$ points$)$: Draw the shear$-$force diagram and determine the maximum shear force. Label all applicable shear forces, distances, and areas of positive and negative shear.

Part C $(8$ points$)$: Draw the bending$-$moment diagram, determine the maximum bending moment, and identify the critical section. Label all applicable bending moments, distances, and areas of positive and negative bending moment. Identify the critical section.

Identify the critical section.
