They are made of conducting material in order to earth it from (neutralize) any excess static charges accumulated on the plane's surface.
Aircraft tires are made of conducting materials to help dissipate the buildup of static electricity that can occur during flight. This is important for safety reasons, as it helps prevent potentially dangerous sparks or discharges when the plane lands. Additionally, conducting tires can help protect the aircraft's sensitive electronics from damage caused by electrostatic discharges.
The electric potential inside an object made from a conducting material is zero.
It depends on the material the ring is made of. If the ring is made of a conducting material such as metal, it will conduct electricity. If the ring is made of an insulating material such as plastic or glass, it will not conduct electricity.
An inclined plane can be made out of various materials such as wood, metal, plastic, or concrete. The choice of material depends on factors like the intended use of the inclined plane, its environment, and durability requirements.
because if the tyres are of metal the will slip
The impedance of plane material is made equal to the impedance of air,in this way the waves sent by radar does not reflect by material of plane and pass through plane and do not come back to radar.That is why,plane remain invisible to radar.This material was invented by a PHD proffesor in UET Lahore Pakistan.
The electicity would create a black hole and destroy the universe
The material that the black box is made of is too heavy. A whole plane made of the same material (All stainless steel), it would have a hard time getting off the ground and would be ridiculously expensive.
Tyres are made corrugated in order to increase the friction between the tyres and the surface of the road. This increases the opposing force incurred by the tyres and hence prevents accidents due to slipping and sliding.
Tigar tyres are made in Serbia. They're considered great value for money.
Because it's the best material for the job.
It is made if non conducting material and its structure traps air which is an excellent insulator in its own right
