The THEORY of MACHINES range enables clear and comprehensive learning of and topics. An understanding of the way in which forces act and react, is fundamental when studying the application of loads on a variety of fixed structures and rotating machinery. The THEORY of MACHINES form a comprehensive range of equipment, equally suitable for demonstration and experimental work.

All the THEORY of MACHINES hardware operates in a standalone mode, with a large number being supplied with Data Acquisition Software.

HTM13 Double Epicyclic Gear Train

Wall mounted apparatus for the calculation and experimental observation of the angular velocity ratios within an epicyclic gear train. Students can also obtain the torque ratios and efficiencies of the gear train also.

HTM17 Crank and Connecting Rod

Apparatus to show the relationship between crank shaft rotation and piston displacement for a fixed "cylinder". The stroke of the connecting rod and hence piston can be adjusted by securing its end to the different fixing points on the radius of the crankshaft.

HTM21 Castor, Camber, King Pin Inclination

This apparatus represents a scale model of the wishbone and king pin arrangement of a front wheel suspension complete with a wheel on an adjustable stub axle. The king pin assembly includes a steering link to demonstrate how a real car works.

HTM22 Relationship between Angular and Linear Speeds

A stepped shaft with three diameters is carried in a bracket which then allows the comparison of the angular rotation of a shaft and the tangential speed at the circumference.

HTM25 Gear Train Apparatus

Understanding the basics of gear trains is important. This apparatus ensures this is done in a simple, visual and durable way. Small, compact and self contained bench top unit for introducing students to gear trains and epicyclic gears.
