railway RRB JE (CBT I + CBT II) Mock Test 2024 Strength of Materials Springs Stress Correction Factor
In a helical coil spring, if C is the spring index, then the shear stress correction factor is given by:
1
\({K_s} = \frac{1}{{2C}}\)
2
\({K_s}=\frac{2C}{{2C+1}}\)
3
\({K_s}=\frac{2C+1}{{2C}}\)
4
\({K_s}=\frac{C+1}{{2C}}\)
