Question 165General Subjects - QMED

The correct answer is B) prevent the user from closing the tool with too much force. The ratchet stop on many micrometers is designed to prevent the user from applying excessive force when closing the tool. This helps protect the delicate internal components and ensures accurate measurements. Applying too much force could damage the micrometer and lead to inaccurate readings. The other options are incorrect because: A) clicking at each increment is the function of the thimble, not the ratchet stop; C) the ratchet stop does not directly stop the spindle from sliding out; and D) the ratchet stop does not eliminate ratchet movement, which is an essential feature of the micrometer's design.
