What is the frictional force between a tire and a road?
the energy to change the shape of the tire were it is crunched is a type of drage
What is the maximum speed with which a 2500 kg car can round a turn of radius 60 m on a level road if the coefficient of static friction between tire and road is 7?
Really? A coefficient of friction of 7? Unheard of. Probably 0.7 Use F = mv^2 / r where F will be the centripetal force as well as the frictional force, (mu)mg. Solve for v.
Coefficient of friction of road and tire?
Coefficient of friction on raod and a tire varies depending on the condition of the road and tyre Wet Road: 0.4 Dry Road: 0.7 This is the average coeffecient for these conditions again it can vary
What force between a bicycle's tires and the road affects the speed of the bicycle?
Answer:When a bicycle is moving upward a force is acting called friction which pulls the rider backward making it harder for the rider to move forward. When the rider is at a constant speed the forces are balanced (the same), when the bicycle is speeding up(accelerating) the forces are unbalanced.The force acting forward is greater. When the bicycle is slowing down the forces going upward and downward are the same, however the force acting backward is greater. The forces are unbalanced when slowing down. When at rest the forces are also balanced. So, overall , the only times when the force's are balanced is when they are either at a constant speed or at rest. The times when the forces that are unbalanced are when the bicycle is slowing down or speeding up.Generally, it is gravity that holds you down, some wind resistance depending on the clothing you wear (as baggy clothes can increase drag) this is why professional cyclists wear those dodgy suits.
How does friction affect the motion of a vehicle in the context of tire surface road conditions including skidding braking force braking distance thinking distance and stopping distance?
Tyre surface: If the tyre is new, it will have surface with depressions which will offer more friction compared to old tyre whose surface-depressions are worn out and it is more flat, so it offers less friction. Therefore, new tyre will have less stopping distance, as force of friction is more. Thinking distance is affected neither by friction between tyre and road, nor by friction between brake and tyre. If road has a wet surface, it has less friction so the vehicle will skid farther, and vice versa. The braking force, i.e, friction between tyre and brake is unaffected by road condition or tyre surface. Hence the distance the vehicle travels WHILE retarding due to "braking force", is not same as stopping distance, because even when the wheels are stopped rotating due to braking force, the car will skid a little distance- this total distance is the stopping distance.
The force that keeps each tire from sliding on the road is called?
traction
What is the frictional force between a tire and a road?
the energy to change the shape of the tire were it is crunched is a type of drage
What force gives wheels traction to grip the road?
Friction between the tire rubber and the road give traction.
Does speed affect the friction between a road and a skidding tire?
Speed does not affect the force of friction.
Why is the force on the steering greater when the tire is flat?
There is more surface area contact between the road and the flat tire translating into more friction between the two surfaces, which increases the amount of force required to change direction.
When you use the handbrakes on a bike what force do you apply?
The force you apply is technically called applied force. It is transfered and used to move the brake pads together. At that point, the frictional force between the brake pads and the tire slows down the tire.
Would the friction between a tire and the road be increased by a wide rather than a narrow tire?
No
What is the part of the tire that actually touches the road called?
The tread.
When is friction a useful force that acts between objects?
Most forms of conventional movement require friction. For example, a car could not go anywhere if not for the the friction between the rubber tire and the road surface.
The weight of a car is 8400N Each tire supports a weight of 2100N The pressure exerted by each tire on the road is 20 Ncm How do you calculate the area of each tire in contact with the road?
Each tire supports 2100 N, and the pressure exerted by each tire is 20 N per centimeter2, so Pressure = Force / Area Pressure = 20 N per centimeter2 Force = 2100 N rearranging the equation for Area Area = Force / Pressure Area = 2100 / 20 = 105 centimeter2 So each tire has 105 cm2 touching the road.
How does tire tread increase friction between tire and road?
tires are made of rubber and rubber can cause friction
What forces created the screeching of tires?
Friction between the tire and the road surface
