Determine the end support reactions for beam B$2.$ Represent this beam as simply supported $($pin

support on one end and roller support on the other$).$ Using a straight edge, draw a FBD to scale and

label: $(6$ points total$)$

$5\mathrm{.}1.$ The beam length $($in ft to the nearest $).(1$ point$)$

$5\mathrm{.}2.$ Label grids $7\mathrm{.}1$ and $5\mathrm{.}4.(1$ point$)$

$5\mathrm{.}3.$ Uniform load for the beam weight, Wwt $($in plf$).(1$ point$)$

$5\mathrm{.}4.$ Uniform load from WTL $($in plf$).$ The uniform load from WTL can be obtained by taking the w TL from

part $2\mathrm{.}3$ and multiplying it by the tributary width from part $3\mathrm{.}2$ to get units of plf$.(1$ point$)$

$5\mathrm{.}5.$ Determine the beam end reactions, R using the formula, R $=($WTL $+$Wwt $)$L$/2($lbs$)$ and your answers

from parts $5\mathrm{.}3$ and $5\mathrm{.}4.$ L is the length of beam B$2.[$Hint: It is possible to determine these by using

the equations of equilibrium $($SMpt $=0,$ SFy $=0,$ and SFx $=0)$ however, since there is symmetry in

the loading, and support conditions $($both ends are pinned$),$ the end reactions are the same.$]$

Give correct magnitude, and units. $(2$ points, $1$ each for magnitude and units$)$ You must show

your work to get credit however if you did part $5\mathrm{.}5$ correctly the end reaction for B$2$ should be

$3,337\mathrm{.}6$ lbs$.$
