Free to revolve upon a Fixed Axis. —The principle of the lever may be extended to the caseof a body of any shape to which forces are applied, pro-vided the body is free to revolve around a fixed axis. The straight line perpendicular to the axis, and con-necting the point of application of a force… … Fig. 48. In Fig. 48, F is the fulcrum, or axis of revolution. Ata and b the forces of /j and f^ are applied. The formeris not perpendicular to its lever arm Fa. To find the moment of /j, we find its component ak,perpendicular to the arm, and take the product Fa X ak = moment.Another and simpler…
