Why do wheels need ball bearings to reduce friction?
because there is grease between them......
What are two ways you can reduce friction in a machine?
A lubricant such as oil and ball bearings are just (2) methods of reducing friction.
What uses a cushion of air to reduce friction?
A hovercraft use a cushion of air to reduce friction. In extreme engineering applications there are also air bearings, bearings where a steady flow of air acts as a lubricant between two very finely machined surfaces to keep them apart.
What are the new techniques being adopted by human beings to reduce energy losses due to friction?
Lubrication and/or bearings, of various types, were the new techniques adopted by human beings to reduce energy loss due to friction.
What friction is the type of friction produced by wheels or ball bearings?
the friction produced by objects such as wheels or ball bearings is called rolling friction
Why are bearings used in bicycles?
To reduce unwanted friction.
What kind of Bearing is a ball or roller anti-friction or plain?
Anti-Friction. Plain bearings have surfaces that rub together, like sleeve bearings. In roller bearings and ball bearings, the surfaces roll and do not (that is, should not) slide. If they slide they destroy themselves quickly.
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).
What are two means by which friction may be reduced?
Lubrication and ball bearings both reduce friction.
How can you overcome friction?
You can't. You can reduce it with lubricants, polishing surfaces, & bearings.
What are the advantages of sliding bearings?
to reduce friction and make the object move smoother.
Three examples of where ball bearings are used to reduce friction?
in machineare parts
Why do wheels need ball bearings to reduce friction?
because there is grease between them......
What are two ways you can reduce friction in a machine?
A lubricant such as oil and ball bearings are just (2) methods of reducing friction.
Material that is applied to reduce friction?
Oil (in car). Grease (in bearings). Silicon. Water.
How is friction reduced in a rolling bearing as compared to a plain bearing?
In case of rolling contact bearings there is either point contact or line contact between rolling elements and races of the bearing depending on whether it is ball bearing or roller bearing... In case of plain or journal bearings contact is generally area contact. Hence friction is reduced in rolling bearing as compared to a plain bearings.
What is ball bearings?
it is a mechanical equipment to reduce friction. It is used in moving parts very often.
