Solution

1. (Question number is not mentioned): The force in member AB will be tension.

Explaination: The members which are loaded longitudinally or in a direction parallel to longitudinal axis are subject to tensile force. Our case is not exception to this.

Q.10 : Triangles are used for trusses becauses of its stability and will not deform easily when subjected to load. Hence, answer will be option number 3.

Q.6 : Ideally the force in member CG will be zero as it is unloaded and supported from both sides.
