Analyze the truss structure shown in Figure $1.$ Specifically, determine the forces in the members $AB,$

$BE,EF,$ and $DH$ as a function of $m$ when $m$ is applied at points $A,B,$ and $C.$ You can assume all angles

are either $45$ or $90.$ If the maximum compression or tensile force each beam can withstand is $4N,$

what is the maximum mass that can "drive" across the truss $($i$.$e$.,$ be applied at A$,$ B$,$ and C$,$ sequentially$)?$

If you were to remove the beams $AE$ and $CF$ from this structure, what would happen $($you do not need

to show calculations$)?$ Using the mass you found in the previous part, do you think the compression or

tensile force would exceed $4N?$

Length $of$ Beams

$AB=BC=CG=AD=AE=CF=11\mathrm{.}5cm$

$DE=BE=BF=GF=17\mathrm{.}0cm$

$DH=GI=EF=24\mathrm{.}0cm$
