In a structural member subjected to torsional loading, elements with faces parallel and perpendicular to the shaft axis are subjected to shear stresses only. True or False?

For a shaft subject to torsional stress, which statement is correct?Group of answer choicesAt the center of the shaft, torsional stress is maximum.Torsional stress does not depend on the applied torque.Torsional stress gradually decreases from the top surface towards the center of the shaft.Torsional stress does not depend on the radius of the shaft.

The maximum torsional stresses will be created:Question 3Select one:a.On the external surface of the shaftb.In the centroid of cross-sectionc.At the supports

Haw the torsional stress can be calculated?Question 4Select one:a.By twisting moment and modulus of elasticityb.By torque and polar moment of resistancec.By torque and area of cross-section

The shear stress formula does not provide accurate results when applied to members having cross-sections that are short or flat. True or False?

When subjected to torsion, a brittle specimen breaks along planes perpendicular to the direction in which tension is a maximum. True or False?Group of answer choicesTrueFalse
