Gears

A 36 tooth driving gear (connected to the motor) is moving a 12 tooth driven gear. What is the gear ratio?... It has a speed advantage.

• 3:1

• 1:3

• 3:3

• 1:1

A 12 Tooth driving gear (connected to the motor) is connected to a 36 tooth driven gear. What is the gear ratio and mechanical advantage?

• 3 : 1 Torque Advantage

• 3 : 1 Speed Advantage

• no Mechanical Advantage

• 1 : 3 Torque Advantage

What's the ratio?

Make sure ratio is reduced

• 5 : 7

• 84 : 60

• 60 : 84

• 7: 5

Looking at the picture, what is the gear ratio?

The arrow indicates the drive gear

• 6 : 10

• 5 : 3

• 10 : 6

• 3 : 5

What's the ratio?

Make sure ratio is reduced

• 1:1

• 84 : 60

• 60 : 36

• 5 : 3

What is the Gear Ratio of a driven gear with 8 teeth and a driving gear with 32 teeth?

Make sure ratio is reduced to lowest terms

• 8 : 32

• 32 : 8

• 1 : 4

• 4 : 1

# of teeth output gear = 30

# of teeth input gear = 60

What is the gear ratio (in lowest terms)?

• 1 : 2

• 30 : 60

• 2 : 1

• 60 : 30

When a input gear is smaller than a output gear you have.....

• Increased Speed

• decreased Torque

• Decreased speed

• No mechanical advantage

Transfers motion between two shafts running parallel to each other. They are characterized by their teeth, which are straight and parallel to the gears axis of rotation.

• Spur Gear

• Worm Gear

• Bevel Gear

• Crown Gear

Conically shaped gears that transmit power between shafts that have intersecting axes of rotation.

• Spur Gear

• Bevel Gear

• Rack Gear

• Crown Gear
