Problem $1(16$ pts$)$

For each of the trusses in Figure $1,$ solve for the reactions and internal forces. Present your final solution $1)$ on a drawing of the truss with the values labeled next to each truss and an indication of tension or compression $($this can be $\frac{T}{C}$ or $\frac{+}{-}),$ and$/$or $2)$ in a table $($example shown below for Truss $($b$)),$ with $\frac{+}{-}$ to indicate if in tension or compression.

$\backslash$table$[[,$Member,N$,$ kips$],[\backslash$table$[[(]],AB,],[$CD$,],[DE,],[EF,],[\backslash$table$[{[}_3.]],AD,],[\frac{?}{\text{b}\text{a}\text{r}}(BE),],[\backslash$table$[[\%]],AC,],[AE,],[BF,]]$

Problem $2(4$ pts$)$

For each of the trusses in Figure $2,$ identify all zero force members. Mark zero force members on a drawing of the truss as shown in lecture notes or in the textbook. Note: You are not given dimensions or values of the loads as you are not being asked to solve for all internal forces, just identify the zero force members $"$by inspection" $-$ no work is needed to be shown.
