Part $4$

Your answer is partially correct.

Use your shear$-$force and bending$-$moment diagrams to determine the maximum positive bending moment, $M_{\text{m}\text{a}\text{x}\text{,}\text{p}\text{o}\text{s}},$ the maximum negative bending moment, $M_{\text{m}\text{a}\text{x}\text{,}\text{n}\text{e}\text{g}\text{,}}$ and their respective locations, $x_{\text{m}\text{a}\text{x}}$ pos and $x_{\text{m}\text{a}\text{x}\text{,}\text{n}\text{e}\text{g}\text{.}}$ Use the bending$-$moment sign convention detailed in Section $7\mathrm{.}2.$ The maximum negative bending moment is the negative moment with the largest absolute value. Enter the maximum negative bending moment as a negative value.$\backslash$end$\{$array$\}\backslash |$ fir $\backslash \backslash$mathrm$\{$ft$\}\backslash$end$\{$array$\}]$

Calculate the reaction forces $B_y$ and $C_y$ acting on the beam. Positive values for the : reactions are indicated by the directions of the red arrows shown on the free$-$body diagram below. $($Note: Since $B_x=0,$ it has been omitted from the free$-$body diagram.$)$

Answers:

$B_y=30\mathrm{.}682$kips

$C_y=14\mathrm{.}3182$kips

Part $2$

Correct

Determine the shear force acting at each of the following locations:

$($a$)x=8\mathrm{.}0-ft($i$.$e$.,$ just to the left of support B$)$

$($b$)x=8\mathrm{.}0+ft($i$.$e$.,$ just to the right of support $B)$

$($c$)x=29\mathrm{.}0ft$

$($d$)x=30\mathrm{.}0-$ ft $($i$.$e$.,$ just to the left of support C$)$

Note that $x=0$ at point $A.$ When entering your answers, use the shear$-$force sign convention detailed in Section $7\mathrm{.}2.$

Answers:

$($a$)V=$ kips

$($b$)V=$ kips

$($c$)V=$ kips

$($d$)V=$ kips
