The equivalent torque for a shaft which is subjected to the combined twisting moment (T) and bending moment (M) is given by equation_________
1
\(\frac{1}{2}\left\{ {\sqrt {{M^2} + {T^2}} } \right\}\)
2
\(\sqrt {{M^2} + {T^2}} \)
3
\(\frac{1}{2}\left\{ {M + \sqrt {{M^2} + {T^2}} } \right\}\)
4
\(\;M + \sqrt {{M^2} + {T^2}} \)
