Apollo Process- Revision test-1

What is the role of the function of transferring the traction and braking forces mean?

• Means the tyre helps the vehicle grip against the road surface

• It allows to move forward, stop and slow the vehicle effectively

• It ensures safe and control driving

• All of the above

Rolling resistance is the friction a tyre creates as it rolls on the road

• True

• False

Fuel efficiency through rolling resistance means

• tyres are designed to reduce of energy required to keep the vehicle moving

• tyres are designed to increase vehicle speed

• tyres improve braking performance

• tyres enhance vehicle aerodynamics

Tires with low rolling resistance are made using advanced materials and tread patterns that allows

• vehicles to use less fuel to maintain speed

• improves fuel economy, reduces emissions

• saves money over time

• All of the above

What is composite membrane?

• A single-layer material used for insulation.

• A material made by combining two or more substances to enhance performance.

• A solid metal sheet used for structural support.

• A natural fiber used in textile manufacturing.

Combination of composite materials makes the tire strong enough to hold air pressure while remaining flexible to adapt to road conditions.

• True

• False

The economic performance of a tyre refers to its ability to minimize operational costs while maximizing its lifespan and efficiency.

• True

• False

The factors that are affect the economic performance of the tyre are

• Fuel efficiency

• Durability

• Maintenance cost

• All of the above

Common materials used in carcasss material used in the tyre which includes polyester which helps in

• flexibility

• strength

• durability

The carcass supports the tyre's ability to handle air pressure, carry the load, and withstand stress during operation.

• True

• False
