sprocket ratio and speed of chain drive

What is the chain ratio if the drive chain has 12 teeth and the driven chain has 60?

• 1:5

• 7:1

• 1:7

• 5:1

Chain drive is more efficient than belt drives.

• True

• False

Chain drive is used for

• Short drive

• Long drive

• Both

• None of the above

chain drive is common in industry because it is more efficient than the v‐belt ( T Or F )
