What is mechanical advantage in gears?
The ratio of output force to input force
The ratio of input speed to output speed
The ratio of input force to output force
The ratio of output speed to input speed
Which gear type is known for its quiet operation and ability to handle high loads?
Spur gear
Helical gear
Bevel gear
Worm gear
If a gear system has a mechanical advantage of 3, what does this mean?
The input force is tripled

What is the effect of a higher gear ratio on speed?
Increases speed
Decreases speed
No effect on speed
Stops the motion
Which gear type is typically used in car transmissions?
Worm gear
Helical gear
Bevel gear
Rack and pinion
If a gear system has a gear ratio of 4:1, what does this mean for the input and output gears?
The input gear rotates four times for every one rotation of the output gear
