How it works
100
Has a gear that rolls on top of a line of teeth.
What is a rack and pinion?
100
Devices built to transmit movement, change a type of motion into another, and change speed or torque.
What are mechanisms?
100
On a bicycle
Where is a chain gear?
100
You compare the number of teeth on the input and output gears.
How do you get the gear ratio?
100
This is present only to reverse the direction of rotation.
What is the idler?
200
It is two gears aligned side by side
What is a simple gear train?
200
motion in a straight line
What is Linear?
200
On a train
Where is a crank and slider?
200
In order to increase torque the output gear must be this, compared to the input gear.
What is larger?
200
Allows you to drastically increase torque and decrease speed continuously in one direction.
What is worm and wheel?
300
It is a small metal piece that bends in the middle.
What is a universal joint?
300
This is the engineering field that deals with mechanics.
What is mechanical engineering?
300
In a hand drill.
Where is a bevel gear?
300
The end result of a device's activity.
What is the output?
300
This gear allows you to transmit rotary motion through an angle greater than 90 degrees.
What is a universal joint?
400
It is a series of at least 3 gears aligned parallel to each other.
What is a simple gear train with idler?
400
Force that acts in a circle or arc.
What is torque?
400
On a vise
Where is a lead screw?
400
To increase the speed of a gear train the output gear must be this, compared to the input gear.
What is smaller?
400
It allows two wheels to rotate at different speeds.
What is a differential gear?
500
It looks like two wheels next to each other with some rope sort of thing circling each one.
What is a pulley and belt?
500
Motion the swings back and forth in an arc.
What is oscillating?
500
On a string instrument.
Where is a worm and wheel?
500
There is an inverse relationship between these.
What is torque and speed?
500
You must have an input, process, and output to have one.
