Description
This versatile kit is part of a series that allows many experiments using diff erent arrangements of their parts. Students, teachers or lecturers fi t the parts of the kit to the work panel (supplied separately) to study or show an engineering science topic. This kit includes diff erent circular section specimens and adjustable chucks for experiments in torsion. Students fi x the specimens in the chucks and apply weights to a lever arm. The arm applies a moment (torque) to one end of the specimen. A scale on the arm shows the angle of twist. Standard tests show the relationship between torsion and ‘J’ (polar second moment of area) value. Students use this to predict the twist angle for any given specimen. The choice of different specimens allows comparisons of diff erent specimen material and how it affects torsion, introducing the modulus of rigidity. Students also move the chuck positions for easy experiments showing the relationship between specimen length and angle of twist. We supplies a CD-ROM with the work panel. It includes all the worksheets, guidance notes and lecturer notes (with answers) needed for typical experiments with each kit. The selection of parts in the kits and the choice of fixing points on the work panel means that teachers or lecturers may extend the experiments to an even greater range. Note: The kit is for use with the ES1 work panel (supplied separately).
