Good Job!
Define a simple machine.
A simple mechanical device that makes our lives easier by changing a force, its direction, its magnitude, or a combination of these.
What is drag?
The force of air pushing back on a vehicle as it moves forward.
What does CAD stand for?
Computer-Aided Design
Why are tracks sometimes better than wheels?
They distribute weight better, so they won't sink into muddy or boggy terrain.
Name three types of engineering other than mechanical engineering.
Possible answers: chemical, material, civil, environmental, electrical, computer, robotics, biomedical,
Name all 6 simple machines
Pulley, Wedge, Wheel & Axle, Inclined plane, Screw, Lever (gear also accepted)
What is pressure?
Pressure is a way of measuring how force is acting over an area.
What is a Rube Goldberg Machine?
A Rube Goldberg Machine is a machine that is intentionally designed to perform a simple task in an indirect and over complicated fashion.
Liquids & gases are both types of _________.
Fluids
Describe an engineering problem you faced this week and how you solved it.
Good Job!
Give a real world example of each of the 6 simple machines.
Instructors use your judgement - very simple responses are probably correct - you can accept a wide variety of answers!
What is the formula for pressure?
Pressure = force divided by the area it's acting on
What is an arduino?
An arduino is a microcontroller, it allows you to add various other components like motors and sensors. The arduino controls the inputs and outputs to these components.
Approximately how long ago were the first combination locks created?
~4000 years ago
Name everybody in this room!
Great Job!
