Question

technician a states that as the abrasive wheel on a grinding wheel wears down, the gap between the wheel and the tool rest decreases. technician b states that if the gap between the grinding wheel and the tool rest is too large, the metal could be pulled into the gap, which could cause the metal to be thrown with much force. who is correct? select one: a. technician a b. technician b c. both a and b d. neither a nor b

Explanation:

As the abrasive wheel wears down, its diameter decreases, so the gap between the wheel and the tool rest decreases, making Technician A correct. If the gap between the grinding wheel and the tool - rest is too large, there is a risk of metal being pulled into the gap and thrown out with force, which makes Technician B correct.

Answer:

C. Both A and B
