The point within the cross sectional plane of a beam, through which the resultant of the external
loading on the beam has to pass through to ensure pure bending without twisting of the crosssection
of the beam is called as-
-
A.
Elastic centre
-
B.
Moment centre
-
C.
Shear centre
-
D.
Centroid
Correct Answer:
C. Shear centre
Explanation:
The shear centre is the specific point in a beam's cross-section where, if a transverse load is applied, the beam will undergo only bending without any accompanying torsion or twisting. For sections with at least one axis of symmetry, the shear centre always lies on that axis. If a load does not pass through this point, it creates a torque that results in the twisting of the structural member.
