Question
Ordinary rubber is an insulator, but the special rubber that is tyres of air crafts are made slightly conducting. Why is this necessary?
- To decrease the price.
- To increase the aircrafts stability.
- To remove the charges generated due to friction.
- Incomplete information.
Hint:
The tyres of aircraft were made slightly conductive to remove the charges generated due to the friction between the tyres and the ground.
The correct answer is: To remove the charges generated due to friction.
This is necessary to remove the charges generated due to friction.
- During landing or departure, tyres with friction on the road create some charges.
- The heat generated due to this may cause harm to the tyres, especially in the case of aircrafts.
- This is owing to the fact that during landing or departure, friction between the tyres and the ground charges the tyres of aircraft.
- And to protect the tyre from the charges caused by friction, the tyres of aircraft were made slightly conductive to compensate for the charges.
