MecMovies 4.0 : M15.2: Principal Stresses in a Tee Beam

scene 7 of 14

The normal stresses produced by a bending moment is computed from the flexure formula:

$σ_{x} = - \frac{M y}{I}$

where $y =$ distance measured from neutral surface, $M =$ bending moment, and $I =$ moment of inertia about the centroidal axis.
