Problem $6$: Determine the forces in the members identified by $"x"$ of the truss shown by the

method of sections.

Problem $7$: Determine the forces in the members identified by $""$ of the truss shown by the

methc $\text{'}$

Hint for Problem $7$: You will need TWO sections. First, take a section through CD$,$ CI$,$ IM$,$ and

MN and find Force in CD$.$ You will need one equation only. Next, think of another section to get

forces DI and IN$.$ Two equations, applied one at a time will give forces in DI and IN$.$
