Mounted Pendulum   (MC-1140)

For experiments on inertia system, investigating Newton's third law. It comprises a circular wooden base, carrying a bifilar pendulum on a frame.

Compound Pendulum   (MC-1141)

This pendulum is used to investigate the relationship between the period of oscillation of a rigid bar pendulum and the distance of its suspension point from its centre of mass. It comprises a steel rectangular bar 1 meter long, drilled at 50 mm intervals. A removable steel knife edge, mounted perpendicularly, a wall bracket is provided for suspension.

Compound Pendulum Reversible, Kater's   (MC-1142)

Comprising ungraduated steel bar 1200 x 10 mm with one pair each light and heavy masses, two steel knife edges set in adjustable metal holders and metal support bracket 1117 drilled for wall mounting.

Guinea And Feather Apparatus   (MC-1143-a)

This apparatus demonstrates that bodies of different density or mass fall through a given distance in the same time in the absence of atmospheric drag.

a) Glass tube 600 x 20 mm, fitted with two solid rubber bungs, one carrying 8 mm dia rubber tube with clip for vacuum connection.
b) Same but Glass tube 600 x 50mm dia.
c) Same as (a) but with stopcock and can be fitted directly on pump plate.

Guinea And Feather Apparatus   (MC-1143-c)

This apparatus demonstrates that bodies of different density or mass fall through a given distance in the same time in the absence of atmospheric drag.

a) Glass tube 600 x 20 mm, fitted with two solid rubber bungs, one carrying 8 mm dia rubber tube with clip for vacuum connection.
b) Same but Glass tube 600 x 50mm dia.
c) Same as (a) but with stopcock and can be fitted directly on pump plate.

'g' By Free Fall Apparatus   (MC-1144)

This apparatus is used to determine 'g' by measuring the time of fall of a steel ball through a pre-determined distance. The time taken being less than one second, a cent! second/milli second timer capable of measuring the time in fraction of seconds has to be used. Comprises two units each of which is mounted on a plastic which can be clamped on a 12 mm diameter retort rod. Connections are taken out to 4 mm sockets. The solenoid unit has a metal core which facilitates prompt release of the sphere on deenergising. The gate switch comprises a hinged steel plate to hold against an adjustable contact by means of a small permanent magnet, the plate falls away promptly at the impact of falling steel ball. The apparatus is supplied with a solenoid unit, gate switch, Steel Ball 18 mm dia and a stand.

Accessory: Centi second timer

Material Kit, Solids   (MC-1146)

Comprises quite a variety of materials in the form of rectangular blocks. This kit is used to make the students familiar with appearance, feel, Texture, hardness and density of a range of common substances.
