Force Method and Shear Analysis

In part two of the force method example problem, the video continues from where part one left off, focusing on solving a second-degree statically indeterminate problem. The instructor applies the moment area method to analyze cases two and three, determining the reactions B Y and C Y. The video concludes with solving for unknown reactions and a preview of the next video, which will cover shear force and bending moment diagrams.
