General Science (NDA) Physics

Why are the tyres of aircrafts made of conducting rubber?

I. So that the charge accumulated on the aircraft in flight, by rubbing the air, can easily be transferred to ground on landing.

2. So that the charge accumulated due to the operation of various electronic equipments in the aircraft in flight can easily be transferred to ground on landing.

Both 1 and 2

Neither 1 nor 2

Explanation:

- Aircraft tires are made of conducting rubber primarily to allow accumulated static charges to be discharged safely upon landing.

- Statement I is correct: During flight, friction with air can cause the accumulation of static electricity. Conducting rubber helps discharge this charge safely to the ground upon landing.

- Statement 2 is somewhat relevant but less specific: While electronic equipment can generate charge, the primary concern alleviated by conductive tires is static discharge from air friction.

Therefore, the most accurate choice is:

Option 1: 1 only
