Find: Determine the maximum tensile and compressive stresses in portion BC of the beam.
For this problem, we have a beam in pure bending where the neutral axis passes through the centroid of the cross section, so we can use the following formula:
where σm is the maximum absolute value of stress, M is the couple moment, c is the distance from the neutral surface, and Ix' is the moment of inertia of the cross section with respect to a centroidal axis (x axis in ...
The expert examines maximum tensile and compressive stresses.
