Gear Ratio Practice

# of teeth input gear = 60

# of teeth output gear = 36

What is the gear ratio (in lowest terms)?

• 36:60

• 60:36

• 3:5

• 5:3

# of teeth input gear = 25

# of teeth output gear = 75

What is the gear ratio (in lowest terms)?

• 3:1

• 2:1

• 3:4

If this gear ratio is 5:3, we have increased:

• speed

• torque

What is the best explanation for a gear train with a 7:1 gear ratio?

• The input gear turns 1 time for every 7 turns of the output gear.

• The input gear turns 7 times for 1 turn of the output gear.

What's the ratio?

• 1:1

• 84 : 60

• 60 : 84

What's the ratio?

• 1:1

• 12 : 84

• 84 : 12

# of teeth input gear = 10

# of teeth output gear = 6

What is the gear ratio (in lowest terms)?

• 6:10

• 3:10

• 10:6

• 3:5

# of teeth input gear = 6

# of teeth output gear = 48

What is the gear ratio (in lowest terms)?

• 1:8

• 8:1

• 6:48

What's the ratio?

• 1:1

• 84 : 60

• 60 : 36

If we have a gear ratio of 1:2, there is increased:

• speed

• torque
