The calf muscle pulls on the foot at point A, which is rotating around point B where the foot contacts the lower leg bones. We want to compute the pulling force FA of the calf muscle necessary for the person to stand on tiptoe as well as the force FB on the lower leg bones from the foot. For simplicity we will assume that the points A, B and C lie on a single line as shown on the simplified diagram on the right. Assume distance dAB = 5.00 cm, distance dBC = 15.0 cm, the angle between the floor and the foot is 0 = 10.0°, and the person's mass m = 80.0 kg.

Two hoops, starting from rest, roll down identical inclined planes. The work done by nonconservative forces, such as air resistance, is zero (Wnc = 0 J). Both have the same mass M, but, as the drawing shows, one hoop has twice the radius as the other. The moment of inertia for each hoop is I = Mr², where r is its radius. Which, if either, has the greater total kinetic energy (translational plus rotational) at the bottom of the incline? Radius=R Mass = M Radius=R Mass = Marrow_forward5.
