With the shoulder flexed at 30 degrees, the moment arm of the deltoid muscle is 1.8 cm. Solve for the force exerted by the deltoid muscle and joint reaction forces at the glenohumeral joint give the following assumptions: The deltoid is the only active muscle at the glenohumeral joint The weight of the humerus is 24 N. The center of gravity of the humerus is located 30 cm from the shoulder center of rotation
