Learning Goal:

Zero$-$force members in a truss usually can be determined by inspecting joints. Identify the unloaded joints in the truss. To start, choose an unloaded joint with the least amount of members connected to it$.$ Then, draw a free$-$body diagram of the joint and determine whether zero$-$force members are present. After evaluating the joint, move on to another joint until all the joints have been evaluated.

Consider the truss shown in $($Figure $1).$ Identify all zero$-$force members.

Check all that apply.
