The Beam Engine is a design based on the principles of a first-class lever. A force is applied to one end of a beam via crank and flywheel, which is pivoted in the middle and the lever transfers the force to create work at the other end of the beam which is connected to a vertically-acting pump. A downward pull on the piston causes the other end of the beam to lift whatever is attached to it, thereby doing”work”. The most common engine was the stationary steam-driven type, but water, wind or other forms of propulsion could be used.
