DYNAMICS TROLLEYS
300 mm long, metal reinforced at ends, having three low- loss ball-bearing wheels and fitted with spring-loaded impulse rod. Rod has three positions to provide different impulses and is triggered by a release pin. With removable metal pins at each end to enable trolleys or masses to be stacked or to provide anchoring points for accelerating cords. Pair. Approximately weight of each trolley 1Kg.

 

INCLINED PLANE, SIMPLE AND FRICTION BOARD.
A planed board, 600x75mm, hinged to the base at one end and provided with a pulley for the force cord at the other. A movable block enables the inclination of the plane to be varied. The friction slide, 100 x 65 mm is reversible and has one side cut away for half its area. Complete with brass roller 75 x 25 mm diameter. Without masses or scale pan.

 

INCLINED PLANE
For experiments on sliding friction. Comprises inclined wood plane, 600 x 100 x 20 mm, with 22 mm diameter pulley, hinged to wood base, 450 x 100 x 20 mm. Linear scale fixed to edge of plane and vertical linear and 0 to 45° angular scales fixed to base with clamp, shaped for use as index. With one each wood blocks, 200 x 75 mm and 100 x 75 mm, steel block 100 x 75 mm, scale pan 75 mm diameter, cord and hooks.
