Question

Technician A says that a special wire brush is needed if it will be rotated at high rpm. Technician B says that some wire brushes have plastic molded into them. Who is right? a. Technician A b. Technician B c. Both A and B d. Neither A nor B

Answer 1

Answer:

Option C

Both A and B

Explanation:

Both technicians are right about what they say about wire brushes. wire brushes are usually made up of steel wire bristles. however, when high RPMs are involved, it is better to get some special types of brushes for that purpose. This is because the heat generated at high RPMs is great, and most times, damages the brush after prolonged use if it is not specially built for such speeds.

In addition that, some wire brushes have plastic hubs which help support the bristles and is usually  attached to the motor.

Considering these, we can say that the Two technicians are right
