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.

HTM9 Simple Flywheel

Wall mounted apparatus to allow students to verify the second law of motion applied to a flywheel i.e. the relationship between torque and angular acceleration. Students can compare experimental and calculated moments of inertia of a disc as well as study the energy transformations.

HTM11 Spur Gear Lifting Machine

The floor or bench mounted apparatus assists in determining the mechanical advantage, velocity ratio, efficiency and limiting efficiency of a single or double gear train.

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.

HTM18 Oscillating Cylinder

Apparatus to determine the relationship between crank angle and piston stroke, the effect of changing crank radius and evaluates the relationship between angular and linear speeds and accelerations.

HTM19 Hooke's Coupling

Apparatus that allows the investigation into the relative angular displacements of shafts at opposite ends of a Hooke's coupling and observes the effect of changing the angles between the axes of the coupling and the interconnecting rod.
