my sister who's in 8th grade apparently just learned about this in science class! a screw is an inclined plane around a cylinder. i couldn't believe that question.

Good to hear, Vegangirl.
I put level as answer but at second thought inclined plane seems ok too.
Hopefully the AAMC people are as well informed as you dad about physics.

Supposedly the answer to the question was in the passage. They gave examples of inclined planes and screw was one of them. At least this is what my friend did to get the answer. I missed it, oh well there goes my 15 in physical.

screws work by rotational force(torque) and so do levers right? that was my reasoning but hell if i know........and another stupid question.....

A screw is an inclined plane. That's just one of those crazy trivial things that I don't know where I heard it but I have never forgotten it. If it makes the difference in a point on my score, then I'd say it was worth it.

I remembered this from Mrs. Stancampiano's eighth grade science class. The one where we all chucked handfulls of crayons across the room at one another. And yes, we had crayons in my eighth grade science class. I'm not quite sure why. Especially in a room filled with monstrous little eighth-graders.

But we certainly learned about screws being inclined planes. Never understood why, but hey, it worked out for me, I guess.

If you have any doubt, just check out the first link posted above. The picture there explains the inclined plane concept very concisely. - Nice job Kazema!

The site in the link calls the screw a modified inclined plane that utilizes a lever, so....I'm confused. I chose lever on the MCAT, and trust me, I got plenty enough wrong already, so I'm not fighting for my chosen answer, I'm just still unclear, and I forget how the question was exactly phrased. I don't understand how lever could be wrong, because even if an inclined plane is involved, and lever certainly is as well.

"if you don't shut up you'll be a cylinder with an incline plane wrapped around it" - high school hoops coach telling me I'll be screwed.


The threads on the screw make it an inclined plane. The head of the screw in combination with the screw driver make it a lever.
