Review

Consider the beam shown in $($Figure $1).$ EI is constant. Assume the support at $B$ is a roller and A and $C$ are fixed.

Part A

Determine the internal end moment: $M_{AB}$ acting on span $AB$ at A measured clockwise.

Express your answer in kilopound$-$feet to three significant figures. Enter positive value if the moment is clockwise and negative value if the moment is counterclockwise.

$M_{AB}=-11\mathrm{.}6k*ft$

Correct

Here we learn how to determine the internal end moment acting on the span of a beam applying slope$-$deflection equations.

Part B

Determine the internal end moment $M_{BA}$ acting on span $AB$ at $B$ measured clockwise.

Express your answer in kilopound$-$feet to three significant figures. Enter positive value if the moment is clockwise and negative value if the moment is counterclockwise.

Part E

Draw the moment diagram. Follow the sign convention given in Chapter $4$ in the textbook.

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

Note $1-$ Draw a vertical line to denote local maximum or minimum.

Note $2-$ You should not draw an "extra" discontinuity line at the point where the curve passes the x $-$axis.

Note $3-$ The curve you choose from the drop$-$down is only a pictorial representation of a real quadraticlcubic curve. The equation of this curve is not mathematically equivalent to the correct answer. Consequently, slopes at discontinuities and intercepts with the x$-$axis $($if any$)$ are not accurate.
