FAQs on Rolling Resistance Video Lecture - Engineering Mechanics - Civil Engineering (CE)
| 1. What is rolling resistance? |  |
Ans. Rolling resistance refers to the force that opposes the motion of a rolling object, such as a tire, on a surface. It occurs due to the deformation of the tire and the interaction of the tire with the road surface.
| 2. How does rolling resistance affect vehicle performance? | |
Ans. Rolling resistance directly affects vehicle performance as it consumes energy and results in the loss of fuel efficiency. Higher rolling resistance requires more energy to overcome, leading to increased fuel consumption and reduced mileage.
| 3. What factors contribute to rolling resistance? | |
Ans. Several factors contribute to rolling resistance, including tire design, tire pressure, road surface conditions, tire material, and vehicle weight. A combination of these factors determines the overall rolling resistance experienced by a vehicle.
| 4. How can rolling resistance be reduced? | |
Ans. Rolling resistance can be reduced by ensuring proper tire inflation, using low rolling resistance tires, maintaining smooth road surfaces, minimizing vehicle weight, and adopting efficient driving practices like avoiding sudden acceleration or hard braking.
| 5. How does rolling resistance impact electric vehicles? | |
Ans. Rolling resistance is a significant factor in the energy consumption of electric vehicles. Higher rolling resistance can lead to reduced range and decreased battery efficiency. Therefore, minimizing rolling resistance is crucial for maximizing the performance and range of electric vehicles.
