STEM Semester Practice Test

The movement of air around the chassis (body) of the race car.

• Wind tunnel

• Airflow

• Pneumatics

• Hydraulics

Mechanical device for lessening the friction or a machine part in whichanother part turns or slides on

• Oil pump

• Piston

• Air foil

• Bearings and bushings

A stage used in the design and problem-solving process to generate a number and a variety of ideas in a noncritical atmosphere.

• Design loop

• Brainstorming

• Process of elimination

• Aerodynamic design

Refers to structural frame of the car that mechanical parts can be attached to.

• Engine

• Windshield

• Chasis

• Transmission

A planning and decision-making process that produces a solution.

• Trial and error

  Design Process

A model used to test and evaluate a design before final production.

• Finished sketch

• Prototype

• Working drawings

• Model

You can help reduce ______ by making sure the axles are free to rotate, and that the wheels and tires are not rubbing on the car body.

• friction

• mass

As an object moves through the air, it is met with air resistance as speeds increase. This air resistance pushes against your CO2 car and prevents it from going as fast as it could in a vacuum.

• Drag

• Mass

• Thrust

A rod that passes through the center of a wheel or group of wheels.

• chasis

• axle

• bushing

In which step of the Engineering Design Process would you share your final design with others?

• ASK

• IMAGINE

• PRESENT

• TEST
