GATE 2023 Strength of Materials Quiz 34

Which of the assumptions are correct in uniform torsion.

Match list-I with list-II and select the correct answer using the codes given below the lists:

Code:

A solid shaft of diameter ‘d’ and length ‘l’ is subjected to torque ‘T’. Another shaft B of some length, material but twice the diameter is subjected to the torque 2T. The ratio of the angle of twist of shaft A to shaft B is _________.

Shaft of 2m length and 50 mm diameter subjected to torque of 8 kN-m and iron weight of shaft causing moment of 5kN-m, what are the principal stress shaft subjected to?

Two shafts having same length and material are joined in series and subjected to a torque of 10 kN-m. If the ratio of their diameters is 2 : 1, the ratio of their angle of twist is –
