The tension coefficient of any member is
[A]. force divided by the length
[B]. tension divided by the length @
[C]. tension per unit area
[D]. tension in the member.
The tension coefficient for a member of a frame is defined as the pull or tension in that member is divided by its length.
t = T/l Where t = tension coefficient for the member, T= Pull in the member, l = Length.
The shiftness factor for a prismatic beam of length L and moment of inertia I, is
The Stiffness factor k= EI/L.
The stress in the wall of a cylinder in a direction normal to its longitudinal axis, due to a force acting along the circumference, is known as
[A]. yield stress [B]. longitudinal stress [C]. hoop stress @ [D]. circumferential stress [E]. ultimate stress.

- The following assumption is not true in the theory of pure torsion :
[A]. The twist along the shaft is uniform
[B]. The shaft is of uniform circular section throughout
[C]. Cross-section of the shaft, which is plane before twist remains plane after twist
[D]. All radii get twisted due to torsion. @
