The Electromagnetic Pump. Magnetic forces acting on conducting fluids provide a convenient means of pumping these fluids. For example, this method can be used to pump blood without the damage to the cells that can be caused by a mechanical pump. A horizontal tube with rectangular cross section (height h, width w) is placed at right angles to a uniform magnetic field with magnitude B so that a length e is in the field. The tube is filled with a conducting liquid, and an electric current of density J is maintained in the third mutually perpendicular direction. Show that the difference of pressure between a point in the liquid on a vertical plane through ab and a point in the liquid on another vertical plane through cd, under conditions in which the liquid is prevented from flowing, is Ap = JeB. %3D

Consider the robotic arm shown below, made up of individual arms AB and BC. The weight of the arms AB and BC are each 160 N, and the resultant weight force is shown to act through each arm's center of gravity as shown. You may assume that the center of gravity is occurring along the midpoint of each arm's length. The robotic arm is picking up a package that weighs 40 N, and the 40 N weight force acts through the package's center of gravity at the location shown. ०८ b) 600 mm 160 N Bo 40° -600 mm 160 N 150 mm 20⁰ 40 N solve the following engineering physics problems with detailed explanations of every step. a) Consider the robotic arm AB. Calculate the moment arm of the individual arm's weight force with respect to the robotic arm's shoulder at point A. Report your answer in mm. Consider the robotic arm BC. Calculate the moment arm of the individual arm's weight force with respect to the robotic arm's shoulder at point A. Report your answer in mm. c) Consider the 40 N package. Calculate…
