collect information about the substances using to reduce the friction in different machines and prepare a report on it
Answers
It can be said that friction must be taken with two surfaces meeting on low shear materials. This should be accessed with lead/copper bearings are some examples.
In order to understand it, it has two metal surfaces within a machine and interacts with each other.
It must reduce friction and rough surfaces produce more friction and smooth surfaces.
Oil, grease, ball bearings etc.
Explanation:
Friction is both boon and bane. Due to friction, we are able to walk, write, type, sit, drive etc. On the other hand, due to friction, there is loss of energy in machinery. Friction is the resistance caused to motion between two surfaces due to interlocking of hills and valleys at microscopic level. If the surface is rough, it will have more friction. In order to reduce friction, we often use lubricants such as oil, grease etc. In some machines, ball bearings are used because, rolling friction is less than sliding friction.
