A shaft is subjected to the combined bending load ‘M’ and torsional load ‘T’, the maximum shear stress at the outer surface of the shaft will be equal to
1
\(\frac{{16T}}{{\pi d^3}}\)
2
\(\frac{{32M}}{{\pi d^3}}\)
3
\(\frac{{16\sqrt{M^2~+~T^2}}}{{\pi d^3}}\)
4
\(\frac{{32\sqrt{M^2~+~T^2}}}{{\pi d^3}}\)
