Bending of Beams
GATE 2008
Easy
The transverse shear stress acting in a beam of rectangular cross-section, subjected to a transverse shear load, is
- Avariable with maximum at the bottom of the beam
- Bvariable with maximum at the top of the beam
- Cuniform
- variable with maximum on the neutral axis
Explanation
For a rectangular cross-section, transverse shear stress follows a parabolic distribution: zero at the top/bottom extreme fibres and maximum at the neutral axis, per τ=VQ/(Ib).
