When a person stands on tiptoe (a strenuous position),the position of the foot is as shown in Figure P8.24a. The totalgravitational force on the body, F, is supported by the forcen exerted by the floor on the toes of one foot. A mechanicalmodel of the situation is shown in Figure P8.24b, where T isthe force exerted by the Achilles tendon on the foot and R isthe force exerted by the tibia on the foot.

The plank is a great way to strengthen abdominal, back, and shoulder muscles. You can also use this exercise position to locate your center of gravity. Holding plank position with a scale under his toes and another under his forearms, one athlete measured that 66.0% of his weight was supported by his forearms and 34.0% by his toes. (That is, the total normal forces on his forearms and toes were 0.660w and 0.340w, respectively, where w is the athlete’s weight.) He is 1.80 m tall, and in plank position the distance from his toes to the middle of his forearms is 1.53 m. How far from his toes is his center of gravity?

A 50 N hand and forearm are held at a 35° angle to the vertically oriented humerus. The CG of the forearm and hand is located at a distance of 12.5 cm from the joint center at the elbow, and the elbow flexor muscles attach at an average distance of 2.5 cm from the joint center. (Assume that the muscles attach at an angle of 35° to the forearm bones.) How much force must the forearm flexors exert if a 50 N weight is held in the hand at a distance along the arm of 25 cm?

When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total is supported by the force n exerted by the floor on the toes of one foot. A mechanical gravitational force on the body, F model of the situation is shown in Figure b, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and 0 when F, = n = 770 N.

When a gymnast weighing 740 N executes the iron cross as in figure (a), the primary muscles involved in supporting this position are the latissimus dorsi ("lats") and the pectoralis major ("pecs"). The rings exert an upward force on the arms and support the weight of the gymnast. The force exerted by the shoulder joint on the arm is labeled Fs while the two muscles exert a total force Fm on the arm. Determine the magnitude of the force Fm. Note that one ring supports half the weight of the gymnast, which is w = 370 N as indicated in figure (b). Assume that the force Fm acts at an angle of 45° below the horizontal at a distance of 4.0 cm from the shoulder joint. In your estimate, take the distance from the shoulder joint to the hand to be L = 71 cm and ignore the weight of the arm.
In exercise physiologystudies, it is sometimesimportant todetermine the location ofa person’s center of gravity.This can be done withthe arrangement shownin Figure P8.21. A lightplank rests on two scalesthat read Fg1 = 380. N andFg2 = 320. N. The scales are separated by a distance of 2.00 m.How far from the woman’s feet is her center of gravity?
The arm in Figure P8.17 weighs 41.5 N. The force of gravity acting on the arm acts through point A.
