Question

The efficiency of a machine can be increased by applying oil grease. why??

Answer 1

Yes this happens because applying grease on machines reduces the friction and the machines work smoothly.

Answer 2

The efficiency of a machine can be increased by applying oil grease because of the following reasons:

• By reducing the amount of friction between the moving parts, lubricants like oil and grease improve the efficiency of simple machines.
• A thin layer of oil or grease is created between the two rubbing surfaces when oil or grease is applied between the moving parts of a machine.
• The two rubbing surfaces are slightly separated from one another by this oil layer, which significantly lessens the interlocking between them.
• Movement becomes more friction-free and smooth. When oil or grease is applied to a machine's moving parts, the surfaces don't rub against one another directly; instead, they rub through the layer of oil and grease.
