Question

What is the value of the amplitude obtained when we use mechanical amplifier?

(a) 1 – 10 µm

(b) 10 – 40 µm

(c) 40 – 50 µm

(d) 50 – 100 µm

The question was posed to me in unit test.

The question is from USM topic in division Mechanical Processes of Advanced Machining

Answer 1

Right choice is (c) 40 – 50 µm

Best explanation: Relatively larger amplitudes are obtained when amplifier is used.
