A timber $[E=1910$ksi beam is loaded and supported as shown. The cross section of the timber beam is $4\mathrm{.}5$ in$.$ wide and $9$ in$.$ deep. The beam is supported at B by a $0\mathrm{.}375-$in$.$diameter steel $E=33900$ksi rod, which has no load before the distributed load is applied to the beam. $[$:$13\mathrm{.}5ft,L_1=15\mathrm{.}5ft$

Determine the deflection at midspan due to the distributed load.

Determine the midspan deflection of the wood beam due to the internal force of steel rod $($F$1).$

Determine the deformation of the steel rod.

Determine the force carried by the steel rod.
