Zero force members has _______ loadings.

• Infinite

• Minimum

• No

• Maximum

The zero forces are used to improve__________ of the structure

• Stability

• Malleability

• Ductility

• Toughness

We find the zero force members by inspections.

• True

• False

If two members of the structure (trusses) form a truss joint and there is no external force acting on that joint then the two members are called___________

• Scalar form of the force vector

• Zero moment member

• The equivalent vector of truss

• Zero force member

If two members of the structure (trusses) forms a truss joint and there is an external force acting on that joint then the two members are called as zero force members.

• False

• True

Which of following is not considered as the true condition for the three members to be zero force members?

• Any two of the three members must be collinear

• They should be joined by a joint

• There must be no external forces acting

• Any two of the three members must be perpendicular

What will happen if the three members are all perpendicular to each other? No external force is applied to them.

• There will be a formation of one zero force member

• There will be a formation of two zero force member

• There will be a formation of two zero force member

• There will be no formation of zero force member

Identify ALL zero force members

• BG

• CF

• DF

• CG

• GF

If a member of force is in negative sign .State

whether the member is in compression or in tension.

• compression

• tension

 

If a member of force is in positive sign .State

whether the member is in compression or in tension.

• compression

• tension
