FORCES KIT This kit includes a set of different plastic shapes for experiments in centres of gravity of two-dimensional objects. It also includes pulleys, weights and a magnetic protractor for experiments in concurrent and non-concurrent coplanar forces and angles. The selection of pulleys and weights allows you to create force triangles, polygons and linked polygons. The guidance notes show how to analyse and predict forces using Bow’s Notation and the parallelogram of forces. 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 (ES1) (supplied separately) to study or show an engineering science topic. Supply a CD-ROM with the Work Panel (ES1). 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. LEARNING OUTCOMES • Centres of gravity • Force triangles • Force polygons and Bow’s Notation • Linked polygons (non-concurrent forces) For this kit we currently have worksheets available for: Forces and Moments (ES2 and ES3): • Centre of Gravity • Triangle of Forces • Principle of Moments • Levers
