Figure shows the anatomical structures in the lower leg and foot that are involved in standing on
Question:
Figure shows the anatomical structures in the lower leg and foot that are involved in standing on tiptoe, with the heel raised slightly off the floor so that the foot effectively contacts the floor only at point P. Assume distance a = 5.0 cm, distance b = 15 cm, and the person's weight W = 900 N. Of the forces acting on the foot, what are the
(a) Magnitude And
(b) Direction (up or down) of the force at point A from the calf muscle and the
(c) Magnitude and
(d) Direction (up or down) of the force at point B from the lower leg b ones?

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
