Angular displacement can be measured suitably by a______________________?
Correct answer: B. Shaft encoder
- A. Linear variable differential transducer (LVDT)
- B. Shaft encoder
- C. Stroboscope
- D. Tachometer
Explanation
A shaft encoder converts angular position or rotation into electrical pulses or coded signals, allowing direct measurement of angular displacement. A tachometer measures speed, while an LVDT measures linear displacement.
