Because $\frac{dM}{dx}=V$ for a positive constant shear, the moment function must have a positive or increasing slope. Also, the moment at $C$ for this beam must be zero.

Part C $-$ Select an appropriate W$-$Section

and economy

Enter your answer using the appropriate beam designation $($e$.$g$.,W867).$ Use the letter $\text{'}$ x $\text{'}$ to denote x in $W867.$

Part D $-$ Check that Tavg $$ Tallow

Enter a numeric value to three significant figures.

View Available Hint$($s$)$ Before proceeding, please review how to draw shear and bending moment diagrams using the graphical method.

Part A $-$ Draw the shear diagram for beam ABC

A steel beam is loaded and supported as shown. Using the graphical method, draw the beam's shear diagram and determine the value of the maximum shear force.

Click on "add discontinuity" to add discontinuity lines. Then click on "add segment" button to add functions between the lines.

NOTE $1-$ You should not draw an "extra" discontinuity line at the point where the shear curve passes the $x-$axis.

A steel beam is loaded and supported as shown. Using the graphical method, draw the beam's moment diagram and determine the value of the maximum moment.

Click on "add discontinuity" to add discontinuity lines. Then click on "add segment" button to add functions between the lines.

NOTE $2-$ Draw a vertical line $($use the "discontinuity line"$)$ to denote local maximum$/$minimum$.$
