This feature in Onshape allows two or more parts to move or stay fixed relative to each other.

What is a mate?

100

This formula is used to calculate the ratio between the driven gear and the driving gear.

What is Gear Ratio = Driven Teeth/ Driving Teeth 

100

This term describes two or more gears meshed together to transmit motion.

What is a gear train?

100

This manufacturing method removes material to create a final part, like milling or laser cutting.

What is subtractive manufacturing?

100

This Avenger created a dangerous AI known as Ultron. 

Who is Tony Stark/Iron Man?

200

This type of mate keeps two parts completely fixed together with no movement.

What is a fasten mate?

200

If a driving gear has 10 teeth and a driven gear has 20, this is the gear ratio.

What is 2:1?

200

This gear type changes the direction of rotation but not the overall ratio.

What is an idler gear?

200

This manufacturing process builds up material layer by layer, as in 3D printing.

What is additive manufacturing?

200

This ship was able to evade the empire numerous times. It is part of a very popular science fiction franchise. 

What is the Millenium Falcon?

300

This mate allows rotation between two parts around a single axis.

What is a revolute mate?

300
An input motor drives a gear that has 10 teeth. That gear then drives a second gear with 5 teeth. This is the type of system. (High Torque or High Speed)

What is high speed system? 

300

If Gear A (12 teeth) drives Gear B (24 teeth), and Gear B shares a shaft with Gear C (10 teeth), driving Gear D (20 teeth), this is the total gear ratio.

What is 4:1?

300

This type of manufacturing changes the shape of material without adding or removing it, like molding or forging.

What is formative manufacturing?

300
This device changed the world in 2007. 

What is the iPhone?

400

This file format is required to send your design to a laser cutter. 

What is .dxf format?

400

If a 12 tooth gear drives a 48 tooth gear, and the motor spins at 600 RPM, this is the output speed.

What is 150 RPM?

400

Gear A (10 teeth) drives Gear B (30 teeth). Gear B shares a shaft with Gear C (8 teeth) that drives Gear D (40 teeth). If the input speed is 300 RPM, this is the final output speed.

What is 20 RPM?

400

This manufacturing process is most suitable for mass-producing identical plastic parts with high precision.

What is formative manufacturing?
400

This pop star became the first artist in history to chart all 10 spots of the Billboard Hot 100 simultaneously.

Who is Taylor Swift?

500

This file format is required to 3D print your design on a slicer. 

What is .stl format?

500

If a 10 tooth gear drives a 50 tooth gear, and the motor provides .3Nm of torque, this is the resulting output torque. 

What is 1.5 Nm?

500

If Gear A (8 teeth) drives Gear B (24 teeth), which shares a shaft with Gear C (12 teeth) that drives Gear D (36 teeth), and the motor torque is 0.2 Nm, this is the total output torque.

What is 1.8Nm?

500

This type of manufacturing process revolves a workpiece while a stationary cutting tool cuts through it. It is typically used to create cylindrical parts. 

What is turning?

500

This pop star became the first artist in history to chart all 10 spots of the Billboard Hot 100 simultaneously.
