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 α. FM

Chemical and Phase Equilibrium

Phase diagrams or equilibrium phase diagrams are the graphical representations that show the phase transformations of the constituting elements with respect to the pressure, temperature, and compositions. The diagrams show the conditions that limit the different phases, namely solid, liquid, and gas. The diagram can also be utilized to verify the relations between the state variables. Most of the phase diagrams are temperature-pressure phase diagrams, with the variable parameter as the composition. Usually other variables such as solubility and pressure parameters are not indicated in the phase diagram. For a one-component system (unary phase diagram), the phase diagram is generally a function of temperature and pressure as the state variables, or temperature and volume. However, for a binary system (two-phase) having two components, the phase diagram is a function of temperature and composition as the state variables only. Coexisting of the different phases of the constituting elements is indicated in the phase diagram. A ternary phase diagram can be characterized by consisting of three phases in equilibrium.
