Engineering Design Process Quiz

My engineering company submits a prototype, but the design ONLY meets 2 out of 4 design requirements. I expect to:

• win the job beating more expensive designs.

• lose the job because I was not at the right price.

• win the job because I met half the design requirements.

• lose the job because I did NOT meet all the design requirements.

Which claim best represents reasoning about friction in the rubber band car?

• The car moved slowly because it looked heavy

• The car travelled further because the new improved axle reduce wheel compared to the original prototype.

• The rubber band wasn't stretched enough

• More rubber bands would make it go faster

Based on the position of the fulcrum, which of these rocks requires LESS force to lift.

• A, where pencil fulcrum is closest to the load.

• B, where pencil fulcrum is in the middle.

• C, where pencil is closest to the force applied by hand.

• None of the above.

What represents a valid piece of evidence in a CER about the egg drop challenge?

• I think cushioning helps eggs survive

• Eggs are fragile and need protection

• The egg survived a drop of 3 meters with foam padding

• Physics principles suggest energy absorption helps
