  4. 4,20 As per the maximum principal stress theory, when a shaft is subjected to a bending moment Mand torque T. And is the allowable stress in axial tension, then the diameter d of the shaft is given by 3 32 (d) d.no[M+GF.T2] [ESE 1997]


  5. 4.28 A shaft of diameter 'd is subjected to bending moment Mand twisting moment T. The developed principal stress will be 16


  6. 4,12 A section of a solid circular shaft with diameter D is subjected to bending moment M and torque T The expression for maximum principal stress at the section is 2M T (a) TD D3 16 MM2+ T2 ESE: 1996]
