Problem $2$:

Consider the truss shown below. State the units for all your answers. Draw a circle$/$box around your answers to highlight the result.

$($a$)$ Identify all zero$-$force members $($show them on the figure below.$)$

$($b$)$ Determine the support reactions at A and B$.$

$($c$)$ Determine the force in the members identified by $"x"$ using the Method of Sections. Indicate whether they are tensile or compressive? HINT: you might need two sections.
