 LEVER CLAMP (KNIFE EDGE CLAMP)

 

For fitting standard meter sticks used in setting up a demonstration balance to study principles of levers, moments, torque etc..

Made of spot welded steel. Designed for fastening to meter sticks by means of knurled set screw and easy viewing of the meter stick. Provided with a removable metal wire stirrup which serves as a weight hanger when placed in an inverted position.

 WHEEL AND AXLE

 

For determining the mechanical advantage and demonstrating the principle of conservation of energy.

Consists of four-step wooden wheel of 35, 50, 65 and 105mm diameters fitted with ball bearings, turning on a single, plated steel rod which can be clamped to a support stand using a right angle clamp. Each wheel has a flat groove to accept several turns of a cord with a small hole at each groove for holding a knotted cord. Can be fitted to a support stand with a right-angle clamp (not included). Recommended for use with nylon twine.

 VERTICAL ACCELERATION DEMONSTRATOR (FALLING BODIES APPARATUS, PROJECTILE APPARATUS)

 

To show that a body launched horizontally will fall vertically at the same rate as a similar freely falling body.

Consists of a push button activated spring-loaded launcher with holes for two steel balls 19mm diameter acting as projectiles. Mounted on a wooden block (l x w x h), 180 x 60 X 30mm. Designed to project one ball forward and the other to fall freely.

Cat. No.

 DOUBLE CONE AND INCLINE

 

For the dramatic and puzzling visualisation of the effect of change of centre of gravity of an object.

Consists of a pair of wooden double ended cones, a wooden diverging bar 0 to 10cm wide, serving as an inclined plane.

When the double cone is set on the bars of the inclined plane the cone appears to roll up the plane violating the law of gravity. This is possible because the axis of the cone is actually moving downward due to a widening of the track.
