consider the loaded truss shown below. identify the zero - force members. drag the appropriate items to…

Explanation:

Step1: Apply zero - force member rules

In a truss, at a joint where only two non - collinear members meet and there is no external load or support reaction at that joint, the forces in those two members are zero. Also, at a joint where three members meet and two of them are collinear and there is no external load or support reaction at the joint, the non - collinear member has zero force.

Step2: Analyze joints one by one

At joint $B$, there are two non - collinear members $AB$ and $BC$ and no external load at $B$, so $BC$ is a zero - force member. At joint $C$, members $BC$ and $CD$ are non - collinear and considering the equilibrium of forces in the $x$ and $y$ directions with no external load at $C$ (after accounting for the already known zero - force member $BC$), $CD$ is a zero - force member. Similarly, at joint $E$, $DE$ is a zero - force member as it is part of a two - non - collinear member joint with no external load. At joint $F$, $EF$ is a zero - force member for the same reason. At joint $G$, $FG$ is a zero - force member.

Answer:

BC, CD, DE, EF, FG
