## Procedure for doing Simulator

##

- Choose any desired environment by clicking on the ÃƒÂ¢Ã¢â€šÂ¬Ã‹Å“combo boxÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢.
- Adjust the sliders to have suitable dimensions for flywheel arrangement.
- Click on ÃƒÂ¢Ã¢â€šÂ¬Ã‹Å“Release fly wheelÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ to start the experiment.
- No of revolutions (N) of the flywheel, after the loop slips off from peg is indicated on the side of axle.
- The time taken by flywheel to come to rest is noted from stop watch.
- Repeat the experiment for different values of variables.

## Procedure for doing Real Lab

##

- The length of the cord is carefully adjusted, so that when the weight-hanger just touches the ground,the loop slips off the peg.
- A suitable weight is placed in the weight hanger
- A chalk mark is made on the rim so that it is against the pointer when the weight hanger just touches the ground.
- The other end of the cord is loosely looped around the peg keeping the weight hanger just touching the ground.
- The flywheel is given a suitable number (n) of rotation so that the cord is wound round the axle without overlapping.
- The height (h) of the weight hanger from the ground is measured.
- The flywheel is released.
- The weight hanger descends and the flywheel rotates.
- The cord slips off from the peg when the weight hanger just touches the ground.By this time the flywheel would have made n rotations.
- A stop clock is started just when the weight hanger touches the ground.
- The time taken by the flywheel to come to a stop is determined as t seconds.
- The number of rotations (N) made by the flywheel during this interval is counted.
- The experiment is repeated by changing the value of n and m.
- From these values the moment of inertia of the flywheel is calculated using equation .

## Observations

Mean value of moment of inertia,I =.........kgm^{2}

## Result

Moment of inertia of the fly wheel =.........kgm^{2}
