A beam engine is a design of engine based on the principles of a first-class lever. A force is applied to one end of a beam, which is pivoted in the middle, and the lever action transfers the force to create work at the other end of the beam.The most familiar example is the type of stationary steam engine used for pumping water from mines. Here the piston of a vertically-mounted cylinder is attached to one end of the beam, to apply the force through upward and/or downward motion. The other end...
A beam engine is a design of engine based on the principles of a first-class lever. A force is applied to one end of a beam, which is pivoted in the middle, and the lever action transfers the force to create work at the other end of the beam.The most familiar example is the type of stationary steam engine used for pumping water from mines. Here the piston of a vertically-mounted cylinder is attached to one end of the beam, to apply the force through upward and/or downward motion. The other end of the beam 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.
