Question

A 10 teeth sprocket is operating at 200 rpm and driving a 25 teeth sprocket through a chain. The pitch of the chain is 20 mm and ultimate strength is 20 KN. Calculate the average linear speed.

(a) 0.55 m/s

(b) 0.66 m/s

(c) 0.77 m/s

(d) 0.88 m/s

I got this question in homework.

The question is from Mechanical Power Transmission in section Mechanical Power Transmission of Farm Machinery

Answer 1

Correct option is (b) 0.66 m/s

The best I can explain: v=\(\frac{TPN}{60}=\frac{10*0.02*200}{60} \)

V = 0.66 m/s.
