The circular rod shown $($Figure $1)$ has dimensions $d_1=6\mathrm{.}6cm,L_1=6m,d_2=4\mathrm{.}6$ cm $,$ and $L_2=5m$ with applied loads $F_1=150kN$ and $F_2=50kN.$ The modulus of elasticity is $E=100$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.

$F_A=\sqrt[\phantom{2}]{V}$alue Units

PART B$-$ CALCULATE DEFLECTION

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

Express your answer with appropriate units to three significant figures.
