What is something useful to reduce friction on wheels and axles?

Lubricants such as oil, grease, and graphite are commonly used. However, simply keeping a liquid coating (even water) may help reduce friction. In many applications, surfaces can be made with very smooth substances such as polished metal, ceramics, or Teflon.

How do you increase the efficiency of pushing a concrete block up a wooden ramp?
Reduce the friction of it and the ramp, for example, mounting it on wheels.
The wheels and gears of a machine are greased in order to decrease?
Friction.
What does friction allow us to do?
In general, friction acts to prevent objects in contact with each other from moving with respect to each other. Friction keeps your furniture where you place it. The friction between your feet [or shoes] and the ground enables you to walk. When you apply the brakes in a car, friction causes the wheels to stop rotating . Friction holds a screw or nail into a board and a nut onto a bolt. Friction between your fingers and an object allows you to pick it up. Friction is proportional to surface roughness. A measurement of the force needed to overcome friction can be used as an indicator of a surface's roughness/smoothness. When friction is used to reduce relative motion (or to get objects moving), a portion of energy needed to do so is dissipated in the form of heat. This is why a car's brakes get hot and why a nail pulled out of a board can feel warm. Usually, this heat is just a waste byproduct, but it can be useful. The friction of rubbing your hands together will warm them, and the heat of driving a nail into a board can be used to temporarily melt the adhesive on 'cement coated' nails.
Can friction produced by wheels of moving train generate electricity?
yes we can produce electricity by fixing dynamo in traction wheels so heat is produced when the friction of train wheel & track so the dynamo generates an power D.C SUPPLY and is converts into Ac supply so we can use that energy for electric trains use of lights and fans....
What can water wheels be used for?
It converts the energy of the flow of water into something more useful. The water wheel can turn a wheel which grinds corn, grain, etc. More modern uses are to converting the energy into electricity. Please give me a trust point.
Do wheels reduce friction?
yes because when they brake the friction is caused to reduce
Wheels help reduce?
friction
What kind of friction can help reduce friction?
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
Why do wheel reduce the force of friction?
Wheels reduces the friction because to improve the speed of the machines. friction can be reduced with the help of the lubricants.
Why do wheels need ball bearings to reduce friction?
because there is grease between them......
Why are ball bearing used in wheels?
Machine parts use ball bearings to reduce friction, making it easier to move the moving parts and producing less wear on the parts.
Are train wheels magnetic?
The wheels on a train are not magnetic. They are steel wheels and the use of steel helps to reduce friction and propel the train forward.
What stuff can reduce friction?
* lubricanting like oil, greese, etc. * by using ball bearing * polishing * stream lining Water can reduce friction. Also, round things like wheels and straws can reduce friction. Things that are placed on wheels, straws, pencils, etc. can move far with a soft push.
Why do wheels help reduce friction between a dresser and bedroom floor?
because the wheels roll,and without the wheels then the bottom of the dresser would just slide and create static electricty,also know as,friction!:)
How do you reduce friction on a bike?
Put grease on your tires or wheels! Hardly no friction! Difficult to run though. Get help from at least two people
How wheels work on a car?
Wheels and axles help reduce friction and allow a heavy objects like a car to move around easily.
How canyou reduce friction?
By gaining lift, adding lubrication, using wheels instead of flat bottom
