Question

What is the value of the amplitude obtained without mechanical amplifier?

(a) 0.0001 – 0.001 µm

(b) 0.001 – 0.1 µm

(c) 1 – 10 µm

(d) 10 – 100 µm

The question was posed to me in quiz.

Asked question is from USM in division Mechanical Processes of Advanced Machining

Answer 1

Right choice is (b) 0.001 – 0.1 µm

The explanation: Relatively very small amplitudes are obtained without amplifier.
