Description
This versatile kit is part of a series that allows many experiments using different arrangements of their parts. Students, teachers or lecturers fit the parts of the kit to the work panel (supplied separately) to study or show an engineering science topic. This kit includes a screw jack (or ‘jackscrew’), a wedge and diff erent bearings. It helps students understand how rotational friction affects the efficiency of popular machine elements and bearing materials. It shows why engineers choose some materials and devices above others for any given application. Students fi t the parts to the work panel and apply eff ort and load weights to find their relative mechanical advantage and effi ciency. The kit introduces students to key engineering terms such as: • Mechanical advantage • Velocity ratio • Effi ciency • ‘Overhaul’ wet 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 fi xing 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 work panel (supplied separately).
