PRECISION GYROSCOPE (0157)
A traditional piece of equipment for exploring the principle of conservation of angular momentum. and other associated phenomena of gyroscope like gyroscopic stabilization. inertial guidance. gyrocompass. principle of precession etc. Comprises a heavy metal roller disc. dynamically balanced. with metal shaft mounted in cone bearings carried on a plastic gimbal ring for smooth. low friction motion. The shaft has a hole towards one side of rotor disc for winding of thread to spin the rotor. This easily removable assembly can either be placed on cradle mounted on simple plain base or on a rocking base for studying the concept of rolling or pitching. Shaft seat has provision on the outside for suspending washers through hook for loading to study the precession. supplied complete with winding cord. S-shaped hook and set of washers for loading.

INERTIAL BALANCE, ECONOMICAL (0159)
Designed to assist in the clarification of relationship between inertial mass and gravitational mass. i. e.. mass and weight. Comprises two sheet metal rectangular platforms of size 130x50mm (width x length] supported by means of a pair of spring steel strips about 300mm apart. One of the platforms has 3 holes for suspending up to three cylindrical masses. Can be clamped to the bench top using G-clamp through the other platform (without hole] and is free to oscillate in horizontal plane under the restoring forces of spring steel strip connectors. Includes 3 cylindrical masses. a G?clamp. and nylon cord. After establishing the spring constant of the balance. with any combination of three masses placed into the slots. change in time-periods of oscillation can be observed by placing one mass at a time. Once calibrated. unknown masses may be measured.

HOOKE'S LAW APPARATUS, SS SCALE (0161)
For the demonstration of Hooke's Law that the elongation produced in a spring within elastic limits is proportional to the load applied to it. Also useful for investigating potential energy and investigating masses. Comprises of a metal rod carrying vertically a polished stainless steel scale 0 to 15cm, with provision for its height adjustment. An integrated mass hanger/pointer is connected to the lower end of the spring with the eye-shaped upper end for suspension through an adjustable collar with cross bar. which is positioned above the scale. Complete apparatus mounted on a stable base.

YOUNG'S MODULUS APPARATUS, ECONOMICAL (0163)
Useful for studying the relationship between load applied to a wire and the resulting extension i.e. Young's modulus of elasticity of the wire material. Can also be used for comparing elastic moduli of two different wires. Two thick sheet metal strips with clamping screws at the top for wires and metal hooks for the loading masses. are mounted in a rectangular plate. ,,- parallel to each other. The plate has a scale 0 - 40 x 1 mm along with a movable Vernier of LC O. 1 mm. attached to one of the metal strips. Also included is a ceiling clamp with a pair of wooden screws for suspending wires from the top and can be attached to a convenient overhead beam or door frame etc. supplied complete with a tension weight and a set of two wires - 1 each of brass and steel

YOUNG'S MODULUS APPARATUS, SEARLE'S TYPE (0164)
A specially designed apparatus capable of greater degree of sensitivity and accuracy. Two cast metal rectangular frames hinged together parallel to each other to allow only vertical relative motion, with a spirit level fixed on a cross-bar pivoted across the frames for noting the reference point. One frame has vertical scale 10-0-1 Omm wit.h a micrometer head along it reading to 0.01 mm for adjusting the spirit level. Each frame has a self?centering chuck at its top for holding wires and load hooks at the bottom. Also included are ceiling bracket carrying a pair of chucks. a counterpoise weight and a set of two wires, one each of brass and steel. The relative displacement between the two frames can be known from the micrometer reading after adjusting the bubble of Spirit Level.
