Proof dV/dx = minus w and dM/dx = V for shear force and bending moment diagrams Part 1

The video tutorial explains two crucial formulas related to internal bending moments and shear forces, emphasizing the need for a solid understanding of calculus. It uses a free body diagram to analyze a finite chunk of a bridge under distributed load, applying the mean value theorem to derive the formulas. The tutorial concludes with a formal proof of the relationship between shear force and distributed load.
