Figure

$1of1$

Determine the displacement $of$ point $C.$ Use the principle $of$ virtual work.

Express your answer $in$ kilopounds times foot cubed divided $byEIto$ three significant figures. Enter a positive value $if$ the displacement $is$ downward and a negative value $if$ the displacement $is$ upward.

$({}_C{)}_v=$

$\frac{k*f{t}^3}{EI}$

Part $B$

Determine the slope $at$ point $B.$ Use the principle $of$ virtual work.

Express your answer $in$ kilopounds times foot squared divided $byEIto$ three significant figures. Enter a positive value for a counterclockwise slope and a negative value for a clockwise slope.

${}_B=$

$\frac{k*f{t}^2}{EI}$
