engineering recuitment GATE CE 2023-24 Test Series Strength of Materials Torsion of Shaft Equation of Torsion
A stepped circular shaft is fixed at A and C as shown in the above figure. The diameter of the shaft along BC is twice that of as along AB. The torsional rigidity of AB is GJ. The torque required for unit twist at B is
1
\(\frac{2GJ}{l}\)
2
\(\frac{5GJ}{l}\)
3
\(\frac{9GJ}{l}\)
4
\(\frac{17GJ}{l}\)
