Answer :
Final answer:
In the context of abrasive wheels and grinders, it is important for the rating of the abrasive wheel to be equal to or greater than that of the grinder to handle the rotational forces and speeds. Therefore, the statement is true.
Explanation:
In the context of abrasive wheels and grinders, it is important for the rating of the abrasive wheel to be equal to or greater than that of the grinder. This is because the abrasive wheel needs to handle the rotational forces and speeds produced by the grinder without breaking or failing.
For example, if a grinder has a rotational speed of 5000 revolutions per minute (rpm), the abrasive wheel should have a rating that can handle or exceed this speed.
Therefore, the statement is true.
