This unit is composed of:
Two outer discs made of aluminum.
Torque transmission is accomplished by mating drive keys of the central disc, located on opposite sides and oriented 90 degrees apart, with the slots of the outer discs. A central disc made of acetal, located between both outer discs. It acts as the torque transmitting element.
Both outer discs are mounted in two rotary elements with a graduated disc to read the angle.
The equipment may be mounted vertically for demonstration purposes, or flat on the bench for experimental use. The crank length is adjustable, and the connecting rod length can be varied. Crankshaft rotation is measured by a rotating protractor scale and piston displacement is shown on a sliding scale. The apparatus shows the relationship between crank shaft rotation and piston displacement, for a fixed "cylinder".
This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Each piece of apparatus is self-contained and compact. A complete instruction manual is provided describing the apparatus, its application, experimental procedure and typical test results.
