The safe twisting moment for a compound shaft is equal to the
The ratio of maximum shear stress to maximum normal stress at any point in a solid circular shaft is
Strain energy stored in a solid circular shaft is proportional to
The value of shear stress which is induced in the shaft due to the applied couple varies
Shear stress induced in a shaft subjected to tension will be
Two solid shafts are made of same material and have their diameters D and D/2. The ratio of strength of bigger shaft to smaller one in torsion is
Compare the strengths of solid and hollow shafts both having outside diameter D and hollow shaft having inside diameter of D/2 in torsion. The ratio of strength of solid to hollow shafts in torsion will be
