TORSION SHAFTS MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS

Byadmin

 TORSION SHAFTS MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS MCQ help in the design and manufacture of shafts. Maximum practical failures occur in shafts because of reversal stresses. Thus its design requires special attention to make it really safe under all conditions. Fig. Torsion of Shafts (a) Shaft is under Torque T, (b) Shaft cross section…

TORSION OF SHAFTS CLASS NOTES FOR MECHANICAL ENGINEERING

Byadmin

TORSION OF SHAFTS CLASS NOTES FOR MECHANICAL ENGINEERING Shafts transmit power. These are subjected to torsion and hence to shear stress. But due to self weight, weight of flywheel/pulley, shafts are subjected to bending. The shaft is in rotation, there comes reversal of stresses. It causes fatigue. Fatigue reduces the strength of shaft. Maximum failure…
