Pick up the correct statement from the following:
The bending moment which when acting alone would produce the maximum stress equal to the major principal stress caused by combined bending and torsion, is called equivalent bending moment
Mcg = (M M2 + r2) where letters carry their usual meanings
Tcp = m2 + T2 where letters carry their usual meanings
The torque which when acting alone would produce maximum shear stress equal to the maximum shear stress caused by the combined bending and torsion, is called equivalent torque
All the above.
