Bending Stress Calculations, Profiles, and Resultants Example - Mechanics of Materials

This video is a good introduction to bending stress calculations using the flexure formula. You'll learn how to calculate bending stress at various points on a cross-section, draw stress distributions, and calculate force resultants. You'll also learn about the similarities and differences for the flexure formula for two different cross-sections.
