engineering recuitment KPSC JE Civil Mock Test 2020 Strength of Materials Torsion of Shaft Effect on Shaft
A circular shaft subjected to torsion undergoes a twist of 1° in a length of 120 cm. if the maximum shear stress induced is limited to 1000 kg/cm2 and of modulus of rigidity G= 0.8 × 106 kg/cm2, then the radius of the shaft should be
1
\(\frac{\pi }{18}\)
2
\(\frac{\pi }{27}\)
3
\(\frac{18}{\pi }\)
4
\(\frac{27}{\pi }\)
