$4\mathrm{.}2$ For the pin$-$connected frame shown,

a$)$ Draw the free$-$body diagram of each member of the frame

b$)$ determine the horizontal and vertical components of the pin forces

c$)$ resolve the pin forces into normal and tangential components

d$)$ draw the shear and bending moment diagrams of each member of the frame.

Note: ABE and DEF are continuous members.
