engineering recuitment ONGC AEE Mechanical Mock Test 2025 Strength of Materials Torsion of Shaft Combined Effect of Bending and Torsion
A shaft is subjected to the combined bending load 'M' and torsional load T. If the permissible shear stress is 'ζ', the diameter 'd' of the shaft will be calculated by the relation
1
d = 16T/πζ
2
d = 32M/πd3
3
d = [16(M2 + T2)1/2/πζ]1/3
4
d = [32(M2 + T2)1/2/πζ]1/3
5
None of these
