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.
Why is grease used in machine?
Grease and oil is used in machinery to prevent the moving parts from wearing out too soon due to friction.
Why is friction between moving parts of a machine undesirable?
Friction between moving parts of a machine leads to energy loss in the form of heat, which can cause overheating and reduce the efficiency of the machine. It also causes wear and tear on the parts, leading to increased maintenance and replacement costs. Additionally, excessive friction can impact the accuracy and performance of the machine.
Scientific word used to describe oiling or greasing a machine?
Lubrication is the scientific term used to describe oiling or greasing a machine to reduce friction between moving parts and prevent wear and tear.
What happens to a machine when it has too much friction?
The excess friction will cause the moving parts to heat up - even to becoming red hot! A cooling system: water, fans and radiator, or lubricating oil, is used to reduce the friction and so lessen the wear and tear on the moving parts.
How does friction reduce the efficiency of machines?
Friction is cased by parts of the machine rubbing past one another. When this happens the parts tend to stick to each other which slows down the machine and heats up the parts. Thus the energy used to drive the machine is diverted from the purpose for which the machine was constructed and the machine becomes less efficient. To reduce friction and make the machine more efficient, lubricants (eg oil) are used to make sure that parts that come into contact can slide past one another more easily. -------------------------------------------------------------------------------- Friction causes machines to slow down, and heat up. effecting efficiency negatively first off excess causes a decrease in speed increase in wear on parts. Also friction causes heat which causes metals to expand. For optimal mechanical efficiency, friction is the enemy. ------------------------------------------------------------------------------------ Friction decreases efficiency. This is because when there is friction, heat is created. Therefore some energy is lost in the form of heat.
Does oil reduce friction?
Yes, Oil forms a coating on the cylinder walls to reduce friction and is also used as a coolant to protect engine parts
Three examples of where ball bearings are used to reduce friction?
in machineare parts
What are disadvantages of heat produced by friction in machines?
energy used for the machine will get lost as heat .machine parts will get worn out.
What do some machine use to lower friction between moving part?
Machines use lubricants such as oil or grease to lower friction between moving parts. These substances create a thin film between the surfaces, reducing direct contact and minimizing friction and wear. Additionally, materials with low friction coefficients, like certain polymers or coatings, can also be used to reduce friction.
How do you describe an oiling or greasing machine?
An oiling or greasing machine is a piece of equipment used for lubricating mechanical parts or components to reduce friction and wear. It typically applies oil or grease to moving parts through automated processes to ensure optimal functioning and longevity of the machinery. These machines are essential in industries where friction reduction is critical for smooth operation.
What is ball bearings?
it is a mechanical equipment to reduce friction. It is used in moving parts very often.
