pleaze help me to this question ​

Please find the answer in the explanation.

Explanation:

Mention three disadvantages of friction between the parts of a machine

Three disadvantages of friction between the part of a machine are;

1. Friction causes wear and tear of machine parts.

2. Friction generates heat between the part of a machine.

3. Friction reduces the efficiency of a machine.

How does.

1 . oiling

2 using ball bearing

To reduce friction, you need to apply a lubricant. Oil and grease are examples of a lubricant. A lubricant helps to reduce friction by making the surface of the machine parts slippery thereby reducing tear and wear.

Also, friction can be reduced by using ball bearing which will allow the rolling of machine parts.
