Answer:
The center velocity of both gears is same & equal to 2034.72

Explanation:
Given data
= 5 cm
= 3 cm
36 rev in 20 sec

= 2 × 3.14 × 1.8
= 11.304

We know that for the set of gears

3 × 11.304
= 6.7824

liner velocity of the first gear

5 × 6.7824
33.912

20.34.72

liner velocity of the second gear

3 × 11.304
2034.72

Therefore the center velocity of both gears is same & equal to 2034.72
