To solve the statics truss problem at joint C using the joint method, it's recommended to first analyze joint B, which has only two unknown stresses, allowing for easier calculations. The equations derived from joint B involve the forces F_AB and F_BD, with angles α and β being critical for the calculations. The angle β has been confirmed as 63.4 degrees, aiding in determining the unknown forces. Once the stresses at joint B are known, they can be used to simplify the analysis at joint C, where only two unknowns will remain. This approach streamlines the problem-solving process and enhances accuracy in finding the required stresses.
