All the members of the planar truss (see figure), have the same properties in terms of area of cross-section (A)

Q. All the members of the planar truss (see figure), have the same properties in terms of area of cross-section (A) and modulus of elasticity (E).

For the loads shown on the truss, the statement that correctly represents the nature of forces in the members of the truss is:

A. There are 3 members in tension, and 2 members in compression

B. There are 2 members in tension, 2 members in compression, and 1 zero-force member

C. There are 2 members in tension, 1 member in compression, and 2 zero-force members

D. There are 2 members in tension, and 3 zero-force members

Ans: There are 2 members in tension, and 3 zero-force members
