What is a gear?
A tool for measuring rotational speed
A type of engine
A device that uses teeth to mesh with other gears
A component that stores energy
What is the purpose of a gear train?
To increase rotational speed
To store energy
To transfer energy and achieve a desired gear ratio
To measure torque
How is gear ratio defined?
The ratio of the speed of the driving gear to the driven gear
The ratio of the torque of the driving gear to the driven gear
The ratio of the number of teeth on the driven gear to the driving gear
The ratio of the diameter of the driving gear to the driven gear
What is a driven gear?
The gear that is turned by the driving gear
The gear that provides input power
A gear that changes the direction of rotation
A gear that measures rotational speed
What is the role of a driving gear?
To be the output gear in a gear train
To measure torque
To be the powered or input gear in a gear train
To change the direction of rotation
What is an idler gear used for?
To increase the speed of rotation
To change the direction of rotation and/or extend the distance between gears
To provide input power
To measure rotational speed
How is rotational speed measured?
In revolutions per minute (RPM)
In meters per second
In degrees per second
In Newton-meters
What does torque measure?
The number of teeth on a gear
The distance between gears
The twisting force that causes rotation
The speed of rotation
Which gear is often connected to mechanical output motion?
Input gear
Driven gear
Idler gear
Driving gear
What is the function of teeth on a gear?
To measure torque
To mesh with other gears and transfer force
To store energy
To increase the speed of rotation
What is the primary function of a gear train?
To store mechanical energy
To transfer energy and achieve a desired gear ratio

What is the relationship between driving and driven gears in terms of gear ratio?
The driving gear always has more teeth
The driven gear always has more teeth
The gear ratio is the number of teeth on the driven gear divided by the number of teeth on the driving gear
The gear ratio is the number of teeth on the driving gear divided by the number of teeth on the driven gear
