Question

A cylindrical shaft made of steel of yield strength 700 MPa is subjected to static loads consisting of a
bending moment of 10 kN-m and a torsional moment of 30 kN-m. Determine the diameter of the shaft
using two different theories of failure and assuming a factor of safety of 2.

Answer 1

Answer:

A cylindrical shaft made of steel of yield strength 700 MPa is subjected to static loads consisting of bending moment 10 kN-m and a torsional moment 30 kN-m. ... = 2 ; E = 210 GPa = 210 × 10 3 N/mm 2 ; 1/ m = 0.25 Let d = Diameter of the shaft in mm.
