How to Find Truss Forces Using the Method of Joints – Statics Trusses – Method of Joints Problem 1

In this video, we solve the truss by finding all the member forces using the method of joints. We also determine if the members are in compression or tension. This problem is solved using static equilibrium of rigid bodies along with the method of joints for trusses, and the property that all forces, internal and external, must cancel and counteract each other so all forces sum to be zero, including reactions at supports.

Problem walkthrough steps: Solve for the reactions of the truss (if not already given) Use the method of joints by isolating a single joint Sum forces at the joint such that equilibrium is kept Determine if members attached to the joint are in tension or compression Repeat process for the other joints in the truss Check the last joint to make sure equilibrium is kept.
