Question

In a stroboscopic method of rotational speed measurement of a machine shaft. If,
N = Machine shaft speed in RPM
n = Number of points on the circuit pattern
F = Number of flashes per min
The speed of rotation N will be

• A. N = F + n
• B. N = F - n
• C. N = F/n
• D. N = F . n

Answer 1

The correct option is C N = F/n

c) N = F/n
