Any bicycle part that makes contact with another part but needs to move to function must have friction reduced. The wheels bearings, steering head, pedal bearings in both the hub and pedal, and the chain links all are designed for minimum friction but they also need lubricant.
What else can I help you with?
Example of man-made system?
Because a bicycle is built thing, built by humans. It's not born from another bicycle, it's not harvested from a bicycle tree / bush /plant. Humans thought them out and humans made them, and they're complicated enough to be called a system.
What force would help you slide down a slide?
Gravity? the strength of the floor?
How rollers reduce friction?
when we are moving on rollers .....only a very small part of the roller is in contact with the ground ......this means only a very smaal part of the rovver get s stuckein the uneven surface of the ground ...as a result there is less friction..!!
Why do motors and engines use oil and grease?
Moving parts in an engine are generally metal on metal and in a car engine everything fits very snugly to eliminate knocking and engine rattle, but this causes extreme friction between the metal surfaces.if you were to run your car without oil, much of the power would be lost to friction and eventually the metals will melt and fuse due to the intense heat and friction. oil serves and a lubricating coat covering most moving engine parts (where metal on metal friction is concerned) so that the metal only has the friction of the oil to cope with, which is negligible.Overall it ruduces running heat, engine wear and increases efficiency, engine life and performance.
Why do bumpers need to absorb more force on today's car?
Yes. Originally, bumpers were merely designed to protect the vehicle from damage. Today, bumpers are designed as part of the shock absorbing system of a car.
What part of a bicycle is a useful friction?
The brakes! And the tires (no friction = no traction).
What part of a bicycle has a small amount of friction?
The bearings
How brakes stop a bicycle?
By creating friction between a moving part and a stationary part.
Where does friction need to be small on a bicycle hub?
In the bearings that go between the stationary part - the axle, and the rotating part - the hub.
How does braking stop a bicycle?
Same as on a car. Applying the brakes means that something stationary is pressed against a moving part. This generates friction, which turns speed into heat.It produces friction, because when the brake touches the rim of the bicycle, the bicycle slows down. (thats called friction) And after a while the bicycle stopsA stationary part is brought into contact with a rotating part. The resulting friction slows the bike down.
Where do you find friction in brakes of a bicycle brake?
A bicycle has high friction at the brakes, first and foremost. Then at places where the rider holds on to the bike, Grips and pedals. Between tires and road.
What is a bike lane?
A bike lane is another term for a bicycle lane or cycle lane - a part of a roadway designed for use by cyclists.
How can you decrase friction?
Depends what you want to increase/decrease friction on. If is like a weight on the floor.. Then to increase the friction all you have to do is increase the weight, To reduce it you either reduce the weight or get a smoother surface, or maybe a cloth in-between the floor and the weight.
If you were a part of a bicycle what part would you be and why?
pedal
What is a bicycle lane?
A bicycle lane is a part of a roadway designated for use by cyclists.
What part of a bicycle resist a pulling force?
The pedals could be one but none thing really resists a pulling force because gravity is a pulling force that acts on everything that has weight.
Can any one part of a bicycle carry out the job of the whole bicycle?
No, that is why there are so many parts.
