This kit helps students understand the concept of moments and principle of lever. It comprises of 5 plywood beams 600 x 45 x 3 mm graduated at 38 mm intervals, and with a groove across its centre to locate the fulcrum point. Also supplied with four fulcurms 32 x 32 x 64mm and 40 metal blanks 25mm square.
This kit is used to understand the concept of elasticity by students. Students can perform experiments on compression, extension, torsion and elastic limits. The kit comprises 2 wide steel springs of 4½ turns 50 mm dia, 25, expandable steel springs with ends bent to form hooks, foam blocks 130 x 50 x 50 mm, one 50 gms reel of 32 S.W.G. copper wire, two 50 gms reels of 26 SWG bare copper wire, one meter length of latex rubber tubing, 4 elastic cords with eyelets and 4 soft erasures for twisting.
It comprises two metal frames connected by a link mechanism carrying a spirit level. The wire under test is held in self centering steel chucks capable of holding wires of 1.2 mm diameter (18SWG). A Micrometer head reading to 0.01 mm is provided for readjusting the sprit level. Supplied complete with ceiling bracket having itself a pair of chucks similar to those on the frame, counter-poise weight. And set of suitable wires, without slotted masses.
This set demonstrates the relationship between density and length for cylinders of the same mass but with different densities. The five 1/2" diameter cylinders are made of copper, aluminum, nylon, polyvinyl chloride, and polyethylene. Cylinders range from 14mm to 120mm long.
