If the anterior and posterior deltoids both insert at an angle of 30 degrees on the humerus and each muscle produces a force of 100N, how much force is acting perpendicular to the humerus? (use sine) - How much force is exerted by the tendon of a pennate muscle when the tension in the fibers is 200N, given the angle of pennation is 70 degrees? - Muscle can generate approximately 100N of force per square centimeter of cross-sectional area. If a biceps brachii has a cross-sectional area of 10 square centimeter, how much force can it exert?
