What is the formula for the bending stress of a cantilever beam?

The formula for the bending stress of a cantilever beam is given by the equation: σ = (M c) / I, where σ is the bending stress, M is the moment applied to the beam, c is the distance from the neutral axis to the extreme fiber, and I is the moment of inertia of the beam's cross-sectional area.

Understanding the Variables

To calculate the bending stress of a cantilever beam, it's essential to understand the variables involved in the formula. The moment (M) is a measure of the force applied to the beam, while the distance (c) is the distance from the neutral axis to the extreme fiber. The moment of inertia (I) is a measure of the beam's resistance to bending. Some key points to consider are:
