Problem $5[40$ Pts$]$

For the determinate truss given below,

a$)$ First, identify any zero$-$force members or$/$and pair of members that have equal axial forces, without performing any calculations but by providing sufficient explanation. $[6$ Pts$]$

b$)$ Calculate the reactions at the supports A and B$.[7$ Pts$]$

c$)$ Determine the axial forces of the members $($AE$),($AF$),($AB$)$ and $($BF$)$ using the Method of Joints. $[15$ Pts$]$

d$)$ Determine the axial forces in members $($DE$),($GE$)$ and $($GH$)$ using the Method of Sections. Determine also whether each computed force is tensile $(T)$ or compressive $($C$).[12$ Pts$]$
