In a simple three- member truss consisting of two rafters and a tie, each member is in
A)compression.
B)tension.
C)either tension or compression.
D)shear.
E)both tension and compression.

Question

Quizplus · Accepted Answer

Each member in a truss can either be in tension or compression, depending on the direction of the external loads and the geometry of the truss. Therefore, choice C, either tension or compression, is the best answer. Shear and both tension and compression are not applicable in a simple three-member truss, as there are no diagonal members in the truss that would create shear or both tension and compression.
