Gear Train Quiz

What is the purpose of Gear Train Videos?

• To demonstrate how gear trains work

• To explain the concept of gear ratio

• To showcase different types of gears

• To teach how to calculate gear teeth

What does the gear ratio represent?

• The number of teeth on the driven gear

• The number of teeth on the driving gear

• The ratio of output torque to input torque

• The ratio of output speed to input speed

If the input gear has 48 teeth and the driven gear has 60 teeth, what is the gear ratio?

• 1:1

• 1.25:1

• 1.5:1

• 1.75:1

If the input gear has 48 teeth and the driving gear has 48 teeth, what happens to the output torque?

• It increases

• It decreases

• It stays the same

• Cannot be determined

If the input gear has 48 teeth and the driving gear has 24 teeth, what happens to the output speed?

• It increases

• It decreases

• It stays the same

• Cannot be determined

What is the main advantage of using a gear train?

• It increases the speed of rotation

• It decreases the speed of rotation

• It allows for different gear ratios

• It reduces the size of the gears

What is the effect of increasing the gear ratio on the speed of the driven gear?

• It increases the speed

• It decreases the speed

• It does not affect the speed

• It makes the speed unpredictable

If the input gear has 36 teeth and the driving gear has 72 teeth, what happens to the output torque?

• It increases

• It decreases

• It stays the same

• Cannot be determined

If the driving gear has 36 teeth and the gear ratio is 1.5:1, how many teeth does the driven gear have?

• 24

• 36

• 54

• 72

If the input gear has 60 teeth and the driving gear has 30 teeth, what happens to the output speed?

• It increases

• It decreases

• It stays the same

• Cannot be determined
