statics

any idea how to analyze trusses? like in method of sections and method of joint thanks in advance

I solved for the loads on a tripod leg that creates a 45 degree angle with the ground. The leg is 2x2" tube. The legs fold up and then swings into open position and stopped by R2. After solving for the loads I rotated the leg to the horizontal position. I solved for the X&Y components. This allowed me to use a beam program with the Y loads and reactions to determine the moment diagram and bending stress. I would then solve for the axial stresses using the X components. I could then combine the bending stress and axial stresses.
