To determine the value of G. It consists of an electronic unit having four sockets and a switch to help hold or release the ball. A heavy retort stand carries a solenoid. When toggle switch is on Catch position, current flows through solenoid producing a magnetic field and holding the ball. The retort stand carries another base. The ball after being released from solenoid fall s on this base. Time taken by the ball to travel from solenoid to second base is recorded in electronic unit.

A steam engine utilises the energy contained in steam under high pressure. The energy that is released when steam expands is made to produce rotary motion which can be used for driving the machinery. The seam form boiler is admitted into the cylinder having a piston , when the steam expands, it causes the piston to move, when the piston has travelled to the end of the cylinder and thus completed the stroke, the expanded steam is allowed to escape form cylinder. At the same time the path of the steam is changed over. i.e. live steam under pressure is admitted to the other side of piston causing the later to travel back past its starting point until it has reached the other end of stroke. A steam engine of this type is called double acting because force of steam is applied alternatively on two sides of piston.
Vertical flask type demonstration model, on metal base. In a two stroke engine, to perform full cycle of operations (changing the contents of cylinder and effecting combustion) two strokes of piston are required. This type of engine is mostly used in petrol driven scooters.It is an internal combustion engine. The thermal energy which is released when fuel is burned is converted into mechanical energy. Petrol is mixed with air in a device called carburettor to form a combustible mixture which is compressed in a cylinder and finally ignited by an electric spark produced between the electrodes of a sparking plug. The gases which are formed in the cylinder by the combustion of air petrol mixture, expand, and thrust the piston downward. Acting through the connecting rod, the piston imparts a rotary motion the crankshaft. The energy to remove spent gases from the cylinder is provided by the flywheel thus paving the way for injection of fresh air petrol mixture, so that a new cycle can begin
University PatternTwo glass tubes one closed at the top and other open are held in clamps which can be locked at any position, clamps can slide on two steel C.P. rods fitted on base, wooden plank carrying an meter scale is mounted on heavy cast iron base with levelling screws, supplied without mercury and rubber tubing
With two Steel C.P. rods carrying clamps, wooden scale fitted on metal strip, two glass tubes mounted on cast iron stand, supplied without mercury and rubber tubing
Wall type. An inexpensive barometer for elementary study of weather, the dial shows mercury pressure equivalent in both English and mill bar scales. It has a hook for suspension and a stationary hand for comparison with previous reading. The movement is housed in a round plastic case.
Small sized, cock, shaped, fitted on base with N W E S arms clearly visible
Cup Shape with Counter. The instrument has a wheel consisting of three conical cups in horizontal plane. The cup wheel spindle is connected by worm gearing to a revolution counter in a waterproof housing. By observing the counter reading at the beginning and end of the period of interest, the average wind speed during the interval can be calculated.
A machine cast aluminium table 10cm dia having a stem of 12cm con be lowered or raised to desired height and it can be tightened wit a thumb screw. In addition to this coarse movement, fine adjustment is provided by a flush in arrangement fitted on a heavy circular base with two levelling screw and one rod to hold capillary clamp, supplied with capillary clamp
