Consider the following statements regarding shear centre:
1) In case of a beam having two axes of symmetry, the shear centre coincides with the centroid.
2) In case of sections having one axis of symmetry, the shear centre does not coincide with the centroid but lies on the axis of symmetry.
3) When the load passes through the shear centre then there will be only twisting in the cross section and no bending.
The correct statements are:
1
1 only
2
1 and 2 only
3
2 and 3 only
4
1, 2 and 3
