What is a gear ratio?
The number of teeth on the driving gear
The number of teeth on the driven gear
The relationship between rotations of driving and driven gears
The difference between the sizes of two gears
Which of the following correctly represents how to calculate gear ratio?
Teeth of driving gear / Teeth of driven gear
Rotations of driven gear / Rotations of driving gear
Rotations of driving gear / Rotations of driven gear = Teeth of driven gear / Teeth of driving gear
Teeth of driving gear × Teeth of driven gear
What happens to torque when a larger gear drives a smaller gear?
Torque increases
Torque decreases
Torque stays the same
Torque becomes zero
In a four-gear train where all gears have the same number of teeth, how will the speed of the final driven gear compare to the first driving gear?
The speed will be doubled
The speed will be halved
The speed will be the same
The speed will be quadrupled
If the driving gear rotates 3 times and the driven gear rotates 9 times, what is the gear ratio?
1:3
3:1
3:9
9:3
If a gear train has a driving gear with 20 teeth and a driven gear with 40 teeth, what is the gear ratio?
1:2
2:1
1:1
4:1
What happens to speed when a smaller gear drives a larger gear?
Speed increases
Speed decreases
Speed stays the same
Speed becomes zero
What is an idler gear primarily used for in a gear train?
To increase the overall speed of the system
To decrease the overall speed of the system
To change the direction of rotation
To increase the overall torque of the system
If the driving gear has 24 teeth and makes 2 rotations, how many rotations will the driven gear with 12 teeth make?
1 rotation
2 rotations
4 rotations
12 rotations
What happens to the speed and torque when two identical gears are meshed together?
Speed increases, torque decreases
Speed decreases, torque increases
Both speed and torque remain the same
Both speed and torque decrease
