Beam Bending Stress
Beam bending stress, abbreviated as \(\sigma \) (Greek symbol sigma), also called flexure, is when a beam is subjected to a load along it's length axis with stress applied perpendicular to the axis.
Beam Bending Stress formula
\(\large{ \sigma_b = \frac{M \; y}{I} }\) |
Where:
\(\large{ \sigma_b }\) (Greek symbol sigma) = bending stress
\(\large{ M }\) = moment about the neutral axis
\(\large{ y }\) = perpendicular distance to the neutral axis
\(\large{ I }\) = second moment of area about the neutral axis (moment of inertia)
