is a square, where the five forces, measured in newtons, are acting on it as shown in the figure. If the system of forces is equivalent to a couple, determine and .
is a rectangle, in which , , and . Forces of magnitudes 225, 275, 265, and 135 newtons act along , , , and , respectively. If the system of forces is equivalent to a couple, Determine the magnitude of the moment of the forces.
is a regular pentagon whose side length is 16 cm. Five forces, each of magnitude 11 N, are acting at , , , , and , respectively. If the system is equivalent to a couple, find the magnitude of its moment, considering the positive direction is , rounded to two decimal places, if needed.
