A shaft to which a cam is fastened or of which a cam forms an integral part, controlling the input of fuel to an engine.

A wheel with a grooved rim in which a rope can run to change the direction of the pull and thereby lift a load.

A machine invented by Eli Whitney in 1793 to remove cotton seeds from cotton fibers, increased cotton production and was a historical factor in the American Civil War.

A rigid bar pivoted about a fulcrum, used to transmit and enhance power or motion.

A device using a hydraulic cylinder to generate a compressive force, utilizing Pascal's Law.

A simple machine that reduces the friction involved in moving objects, fundamental for transportation and machinery.

An engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid.

A part of an engine which translates reciprocating linear piston motion into rotation, fundamental in converting motion.

A flat surface tilted at an angle to help raise or lower loads, significantly reducing the force needed.

A heavy rotating disc which is used to smooth out power delivery and store rotational energy.

A rotating machine part having cut teeth, which mesh with another toothed part to transmit torque and speed.

An engine that uses the expansion or rapid condensation of steam to generate power, a driving force behind the Industrial Revolution.

An inclined plane wrapped around a cylinder, used to convert rotational force to linear force and motion.

A machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.

A machine tool primarily used for shaping pieces of metal (or occasionally other materials) by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing a cutting action.

A gear train with three shafts that has the property that the angular velocity of one shaft is the average of the angular velocities of the others, or a fixed multiple of that average.

The process of moving heat from one location to another by the use of vapor compression or absorption cycles.

A mechanical device that extracts thermal energy from pressurized steam and converts it into rotary motion, widely used in power generation plants.
