ES4 DEFLECTION OF BEAMS AND CANTILEVERS KIT Vocational Training Equipment Mechanical Experiment Equipment
DEFLECTION OF BEAMS AND CANTILEVERS KIT This kit includes different beams and fixing blocks. The fixing blocks work as clamps or knife-edge supports. They hold the beams in different ways, such as a cantilever, simply supported, fixed (encastre) and a propped cantilever. Students set up a beam on the supports and add weights to deflect the beams. An accurate dial indicator measures the deflection at the point of loading. The choice of different beams allow extra experiments, showing the relationships between beam deflection and ‘I’ (second moment of area) value. They also allow comparisons of different beam material and how it affects deflection, introducing Young’s Modulus. Students also use the cantilever for easy experiments showing the relationship between beam length and deflection. 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 digital versions of 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.
