Re: Lever Task
I would figure so, the levers are the ones transferring the energy.Ashernoel wrote:My teammate is asking if we can use marbles in between the levers.
“A lever hits a marble which goes and hits a lever”
Is that ok?

Lever Question
Hey guys.
I was wondering, for the lever system, do our levers need to travel a certain direction (clockwise or counterclockwise) to count as their class of levers? Or is it just the direction of the effort and load? For example, If I wanted to mount a second class lever in such a way where the effort forced down the long end and not up, would that be acceptable?

Re: Lever Question
As long as the levers are acting in the way specified by their class, with the effort and load moving in the same directions as shown, it should be fine, at least in my experience. At my first invitational, our levers only moved a few centimeters each and they were legal. Maybe you could provide a diagram of your proposed lever?Ash123 wrote:Hey guys.

Re: Lever Task
What are people's feelings on a lever that has the effort and load at the same point on the lever? I don't think this classifies as a lever but the discussion came up

Re: Lever Task
I don’t think that would count. A second class lever requires the load to be in between the effort and fulcrum, while a third class lever requires the effort to be in between the fulcrum and load.ScottMaurer19 wrote:What are people's feelings on a lever that has the effort and load at the same point on the lever?

Re: Lever Task
I concur. It will have no mechanical advantage whatsoever so if it even counts as a class of lever it won't satisfy the need to use mechanical advantage.Ash123 wrote:I don’t think that would count.

Re: Lever Task
That’s actually something that confuses me about the rules- how do you know of the lever has some mechanical advantage? And do all of the mechanical advantages have to be the same?davecutting wrote:I concur.

Re: Lever Task
If the load and the effort are not in the same position, you will have mechanical advantage. That is, a mechanical advantage other than one.Ash123 wrote:That’s actually something that confuses me about the rules- how do you know of the lever has some mechanical advantage?
