Gear ratio practice

When speed increases, what happens to the value of torque?

• increases
• decreases
• stays constant

When speed decreases, what happens to the value of torque?

• increases
• decreases
• stays constant

When speed is constant, what happens to the value of torque?

• increases
• decreases
• stays constant

A gear ratio is defined as which of the following?

• Teeth of gear : teeth of gear
• gear shape : gear shape
• Speed : torque

What is the function of the smaller gear?

• Makes the output gear turn slower
• Makes the output gear turn faster
• Makes the larger gears turn in opposite directions.
• Makes the larger gears turn in the same direction.

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

• Increased Speed

• Increased Torque

What is the mechanical advantage of this gear ratio?

• 1: 3 Torque Advantage

• 1: 3 Speed Advantage

• no Mechanical Advantage

What is the mechanical advantage of 1:5 gear ratio?

• Torque Advantage

• Speed Advantage

• no Mechanical Advantage

If the small gear is input gear, what is happening to the torque?

• Increase

• Decrease

• Remains constant

• Not enough information

# 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
