When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure a. The total gravitational force on the body, Fe, is supported by the force n exerted by the floor on the toes of one foot. A mechanical 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....
read the question carefully please. A 10 000-N shark is supported by a cable attached to a 4.00-m rod that can pivot at its base. Calculate the ten sion in the tie-rope between the wall and the rod if it is holding the system in the position shown in Figure P12.49. Find the horizontal and vertical forces exerted on the base of the rod. (Neglect the weight of the rod.) where T is the force exerted by the Achilles tendon...

A 75 kg person is crouching with his weight evenly distributed on both tiptoes. The forces on the skelet part of foot are shown in Fig. 12.9 below. In this position, the Achilles tendon experiences a force F., making an angle a = 59.2° with the horizontal. The tendon acts on the ankle a horizontal distance d= 9.66 cm from the point where foot touches the floor. The tibia acts on the foot with magnitude | F and makes an...
