The image depicts a conceptual diagram of the force plate’s function. A square has downward facing arrows at each of its four corners. Beginning at the upper left corner, the arrows are labeled with F1, F2, F4, F3 in the clockwise direction. Below the diagram equation there are equations for the calculation of Xcop and Ycop. The equations read as follows: Xcop equals x sub zero plus the quantity: F 2 plus F 4, multiplied by d x, divided by F total. Ycop equals y 0 plus the quantity: F 1 plus F 2, multiplied by d y, divided by F total. x 0 is the horizontal distance from the left edge to F 3. d x is the horizontal distance from F 3 to F 4. y0 is the vertical distance from the bottom edge to F 4. d y is the vertical distance from F 4 to F 2.
