Question

The shear centre position of a thin-walled symmetrical channel section will lie

• A. on the centroid
• B. very close to the centroid
• C. between the centroid and the web mid-point
• D. away from the web, on the line of symmetry

Hint:

Understanding the location of the shear centre is key to avoiding torsional deformation when applying transverse loads to thin-walled structures.

Answer 1

The Correct Option is D

The shear centre of a symmetrical channel section is typically not located at the centroid but is offset away from the web towards the open face of the channel. This position is crucial for understanding where to apply a load to avoid inducing torsion in the section.
