Due to this, the light does not reach to the eye piece as shown in Figure c. Auth with social network: Share buttons are a little bit lower. Rotational Dynamics In pure translational motion, all points on an object travel on parallel paths. To make this website work, we log user data and eynamometer it with processors.

The dynammometer block has a long lever attached to it and carries a weight W at its outer end. Nirmal Kushwaha Mechanical Deptt. To make this website work, we log user data and share it with processors.
The upper end of the ropes is attached to a spring balance while the lower end of the ropes is kept in position by applying a dead weight as shown in Figure.
Auth with social network: In the transmission dynamometers, the energy is not wasted in friction but is used for doing work. There is another pulley B called driven pulley mounted on another shaft to which the power from pulley A is transmitted. About project SlidePlayer Terms of Service. It is thus obvious that the frame causes movement about E in the anticlockwise direction.
The pinion revolves freely on a lever. A helical spring is provided between the nut and the upper block to adjust the pressure on the pulley to control its speed. The energy or power produced by the engine is transmitted through the dynamometer to some other machines where the power developed is suitably measured.
It consists of a pulley A called driving pulley which is rigidly fixed tothe shaft of an engine whose power is required to be measured. Published by Shanna Daniel Modified over 2 years ago.
In the absorption dynamometers, the entire energy or power produced by the engine is absorbed by the friction resistances of the brake and is transformed into heat, during the process of measurement.
The frame is pivoted at E and its movement is controlled by two stops S,S. A counter weight is placed at the other end of the lever which balances the brake when unloaded. Prony brake dynamometer 2. Related Posts

Compound planetary gears[ edit ] Stepped planet series of the Rohloff Speedhub internally geared bicycle hub with the smaller planet series meshing with the sun wheel and the larger planet series meshing with the ring gear. Some designs use "stepped-planet" which have two differently-sized gears on either end of a common shaft. The small end engages the sun, while the large end engages the ring gear. This may be necessary to achieve smaller step changes in gear ratio when the overall package size is limited. Compound planets have "timing marks" or "relative gear mesh phase" in technical term.
Voodoobei A helical spring is provided between the nut and the upper block to adjust the pressure on the pulley to control its speed. We think you have liked this presentation. In order to balance it, a weight W is applied at a distance L from E on the frame as shown in Figure. The most general motion is a combination of translation. If you wish to download it, please recommend it to your friends in any social system. At every revolution of the shaft, a flash of light is projected through the slot in the disc A An eye piece E is fitted behind the disc B on the shaft bearing and is capable of slight circumferential adjustment.
