Yes, shoulder adduction can illustrate a class three lever. In this scenario, the shoulder joint serves as the fulcrum, the effort is applied by the muscles contracting to bring the arm down towards the body, and the load is the weight of the arm itself. Class three levers are characterized by the effort being applied between the fulcrum and the load, which is the case in shoulder adduction.
