Problem $3$

The U$-$shape shown below has the dimensions shown; the shear force, $V,=2\mathrm{.}5kN.$ Use this information to determine the answers for parts $($a$)-($d$).$

Problem $3$

Part $($a$).$

Divide the composite shape into a series of simple shapes, solve for the moment of inertia for each simple shape, and sum up the results to get the moment of Inertia for the composite shape $($like was done in Chapter $6$ of the text.$)$

For the answer below, enter the number as an integer $($ex: $12,345)$ and NOT in scientific notation $($do not enter as $1\mathrm{.}23{10}^4$ or $1\mathrm{.}23e4.)$

The moment of Inertia of the solid circular shape $($in $m{m}^4)$ is:

Problem $3$

Part $($b$).$

Ap is the area of the part of the crosssection that lies away from the axis where $V$ is to be calculated.

The value of $Ap($in $m{m}^2)$ is:
