Calculating Bending Stress

The bending stress is a critical component of beam stress calculation, and it occurs when a beam is subjected to a bending moment. The bending stress can be calculated using the formula σ = (M y) / I, where σ is the bending stress, M is the bending moment, y is the distance from the neutral axis to the point of interest, and I is the moment of inertia.

Calculating Axial Stress

The axial stress occurs when a beam is subjected to an axial load, which can cause the beam to stretch or compress. The axial stress can be calculated using the formula σ = F / A, where σ is the axial stress, F is the applied force, and A is the cross-sectional area of the beam. The key steps to calculating axial stress are:

1. Calculate the applied force using the formula F = P / A, where P is the applied pressure and A is the cross-sectional area of the beam.
