R.p.m. indicator
Answer:
TACH
Hint:
["Think of the device that measures engine speed."]
Explanation:
The clue "R.p.m. indicator" leads to the answer "TACH" through a straightforward definition. In the context of engines and machinery, "r.p.m." stands for "revolutions per minute," which is a measure of the frequency of rotation. A "tachometer" is an instrument that measures this rotational speed. Therefore, "TACH" is short for "tachometer," making it an indicator of r.p.m. This clue is a direct reference to the function of a tachometer, without any additional wordplay or puns.
