(15 points) Find the tension in the Achilles tendon and the force that the tibia exerts on the ankle joint when a person who weighs 750N supports himself on the ball of one foot. The normal force N = 750N pushes up on the ball of the foot on one side of the ankle joint, while the Achilles tendon pulls up on the foot on the other side of the joint.

(10 points) In the movie 7erminator, Arnold Schwarzenegger lifts someone up by the neck, with both arms fully extended and horizontal, holds the person off the ground. If the person being held weighs 700N, is 60 cm from the shoulder joint, and Arnold has an anatomy shown in the figure, what force must each of the deltoid muscles exert to perform this task? Assume that each Arnold's arm weighs 30N. . Deltoid muscle Humerus Scapula . 27.5m
