has dimensions $d_1=7\mathrm{.}8cm,L_1=6m,d_2=3cm,$ and $L_2=5m$ with applied loads $F_1=100kN$ and $F_2=60kN.$ The modulus of elasticity is $E=95$GPa. Use the following steps to find the deflection at point $D.$ Point $B$ is halfway between points A and $C.$

Part A $-$ Reaction force

What is the reaction force at $A?$ Let a positive reaction force be to the right.

Express your answer with appropriate units to three significant figures.

$F_A=$

Part B $-$ Segment the rod

For the given rod, which segments must, at a minimum, be considered in order to use $={\displaystyle \underset{?}{\overset{?}{}}}\frac{NL}{AE}$ to calculate the deflection at $D?$

Check all that apply.

$CD$

$BD$

$BC$

$AC$

$AD$

$AB$

Part C $-$ Calculate the deflection

What is the deflection of the end of the rod, $D?$ Let a positive deflection be to the right.

Express your answer with appropriate units to three significant figures.
