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

Working Principle of laboratory ball mill When the laboratory ball mill works, motor and speed reducer transmit torque force to big and small gears of laboratory ball mill, so the barrel rotates.When the barrel rotates, Steel balls or other grinding media in the barrel are lifted to a certain height and fall down freely, so materials in the barrel are impacted. Grinding media mixing with materials impact and grind materials continuously. The grinding media and materials impact and grind each other when the laboratory ball mill rotates continuously. The final product will be discharged from outlet when it meets the request, so the grinding process is finished application range, simple structure and convenient maintenance.
