Pick up the correct statement from the following :
The point through which the resultant of the shear stresses, passes is known as shear centre
In the standard rolled channels, the shear centre is on the horizontal line passing through and away from the C.G. beyond web
In equal angles, the shear centre is on the horizontal plane and away from the C.G., outside of the leg projection
In T-sections, the shear centre is at the C.G. of the section
All the above.
