If n=2 (rpm of bull wheel), l=3 mm (length of cutting stroke) and m=5 (ratio of return time to cutting time), find the value of cutting speed in mm/minute.
Correct Answer: C — 0.36
Explanation:
C.S. = nl (1+m) / 100. Here l=3mm, n=2, m=5. So by putting these values in the above equation we can easily get the answer as 0.36.
