Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

A person stands on the ball of one foot. The normal force due to the ground pushing
up on the ball of the foot has magnitude 750 N. Ignore the weight of the foot itself.
The other significant forces acting on the foot are the tension in the Achilles tendon
pulling up and the force of the tibia pushing down on the ankle joint.
Gastrocnemius-
soleus muscles
FAchilles
Achilles tendon-
Calcaneus
(heel bone)
Tibia

If the tension in the Achilles tendon is 2234 N, what is the force exerted on the foot
by the tibia? If the force is upward, enter a positive value. If the force is downward,
enter a negative value.

Two children playing on a frictionless garden gate invent a new game called "gate." The idea is that they will get on opposite sides of the gate and each push such that the gate does not move. If they both push horizontally and perpendicular to the gate and one child pushes with a force of 180 N at a distance of 0.580 m from the hinges, determine the force the second child must exert in order to keep the gate from moving if she pushes at a distance of 0.280 m from the hinges.

If you hold your arm outstretched with your palm upward, the force to keep your arm from falling comes from your deltoid muscle. Assume that the arm with hand has mass 4.25 kg and the distances and angles shown. What force must the deltoid muscle provide to keep the arm in this position, in Newtons? Use g = 10.0 m/s². Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, is already given in the question statement. Deltoid 17 cm 38 cm

Unlike most of the other muscles in our bodies, the masseter muscle in the jaw, as illustrated in the figure, is attached relatively far from the joint, enabling very large forces to be exerted by the back teeth. This is shown in the figure below, where a person is biting down on a bullet placed between the back teeth. (FM = 295 N and rR = 4.0 cm.) (a) Using the information in the figure, calculate the magnitude of the force exerted by the teeth on the bullet._________ N(b) Calculate magnitude of the force on the joint._________ N
Question 1) The figure shows a person wearing weight boots and doing lower leg flexion/extension exercise in sitting position to strengthen the quadriceps muscles and a simple mechanical model of his leg. W 1 is the weight of the lower leg, Wo is the weight of the boot, FM is the magnitude of the pulling force exerted on the tibia by the quadriceps muscles through the patellar tendon, F, is the magnitude of the reaction force acting on the tibiofemoral joint. Point O is the center of the tibiofemoral joint, Point A is the point where the patellar tendon attaches to the tibia, Point B is the center of gravity of the lower leg, C point of gravity is the center of gravity of the boat. The distances between point O and points A, B and C were measured as a = 10 cm, b=22 cm and c=43 cm, respectively.
