Problem 7.26 - Graphical Methods for Shear Force & Bending Moment Diagrams

Problem Statement

Plot the shear force and bending moment diagrams for the loading shown. Assume w = 30 kN/m, L₁ = 3.6 m, and L₂ = 1.2 m. What is the maximum absolute shear force and maximum absolute bending moment?

Figure 1: A beam is subjected to a distributed load with supports at A and B.
