Her foot pivots as a single structure about a single pivot in her ankle. When she stands on tiptoe, her foot pivots about her ankle. As shown in the foot diagram and the free-body diagram below, the forces on one foot are an upward force on her toes from the floor, a downward force on her ankle from the lower leg bone (called the Tibia), and an upward force on the heel of her foot from her Achilles Tendon. Suppose a 61.3 kg woman stands on one foot, on tiptoe, with the sole of her foot making a 25.0 degree angle with the floor, and with the distances are as shown in the figure.
A beam resting on two pivots has a length of L = 6.00 mand mass M = 87.0 kg. The pivot under the left end exerts a normal force n1on the beam, and the second pivot placed a distance ℓ = 4.00 m from the left end exerts a normal force n2. A woman of mass = 61.5 kgsteps onto the left end of the beam and begins walking to the right as in the figure below. The goal is to find the woman's position when the beam begins to tip. (b) Where is the woman when the normal force n1 is the greatest?x = ________m(c) What is n1 when the beam is about to tip?__________ N(d) Use the force equation of equilibrium to find the value of __________n2 when the beam is about to tip. __________N(e) Using the result of part (c) and the torque equilibrium equation, with torques computed around the second pivot point, find the woman's position when the beam is about to tip.________x = m(f) Check the answer to part (e) by computing torques around the first pivot point.________x = mExcept for possible slight…
A board sits in equilibrium. On the left end, there is a wire that supports the board from the ceiling, and to the right, there is a sawhorse that supports the board from the ground. The sawhorse is a distance d= 1/5l from the right edge of the board. There is a block with mass ms= 4.5kg that is a distance 3/4l from the right edge of the board. Finally the board has a mass mb= 11kg. c) Write down Newton's 2nd law. Put the equation in terms of mb, ms, g, T, and Fn. Where T is the tension in the wire, and Fn is the normal force of the sawhorse on the board. d) Write down Newton's 2nd Law for rotations. Put the equation in terms of l, mb, ms, g, T, and Fn.

Question 3) The position of the head and neck and the forces acting on the head are shown in the figure. the center of gravity of the head with a mass of m-9 kg is located at point C. Neck extensor muscles November 21, 2016 by making a y=55° angle with the vertical from point B to the skull, the neck muscle force with a intensity of FmNovember85N is affected. The center of the atlantooccipital joint is located at point B takes. For this flexion position of the head, F, which makes an angle a with the bed from point A, is influenced by the joint response force. (g take the gravitational acceleration as 9.81 m/s2.) According to this; a) Calculate the angle a where the Fjeklem reaction force is built with the horizontal. b) Calculate the Fjeklem reaction force. (Write your result in unit N.) W FM
