Question

Which statement is not correct regarding the deformation of a circular shaft in torsion? a. Cross sections remain flat. b. Longitudinal lines remain straight. c. Circular sections remain circular. d. Radial lines on the sections remain straight.

Answer 1

B

Step-by-step explanation:

Torsion is application of torque to a shaft to turn it about its longitudinal axis. When torque is applied to a shaft the circle remains unchanged in a circular state, its cross section does not warp but remains flat with a straight radial lines but its longitudinal lines changes into an helix intersecting the circular shaft
