General Mission Possible

so basiclly what tht task is telling you to do is have a lever with an ima greater than one and have it use that power or force in a way that distributes a action that has a ima greater then 1? to simplify activate a lever with an ima greater than 1

Kind of, but the important part of the rule (which may be confusing) is probably "in a manner that requires..." It is relatively easy to build a lever with an IMA greater than 1 (just shift the fulcrum away from the center on a 1st class lever). But it is much different to actually utilize that IMA in a productive manner. For example, you might use a 100g mass applied to a 5 IMA lever to lift a 25g mass, but you didn't need the IMA of 5 to complete the task. However, if the mass you were lifting was ~500g, you would have needed the large IMA.

OH ok i think i get it. If the task states to use the lever so it uses 5 IMA not just make a lever that is capable of having a 5 IMA. We would be able to make a lever with an IMA of 10 fr example as long as we reach the point of at least 5 IMA, am i correct?

Submit an official clarification.

oh yeah i guess i forgot to mention that srry. I was wondering if it was legal to pour the material from a higher container if that container starts lower but then i raise it up.

Do you think that would be allowed within either the actual wording of the task or the spirit of the task? I recommend rereading task 4.j. closely.

Literally, how the heck can you pour material from one container into another container higher in the device? I would think you need to transport the granular material up somehow, but does that constitute pouring from one container to another? Maybe I am a little dense but can someone give a simple scenario where it is legal to do this?

Edit: Wait, it actually says "Move and pour", so I guess that means that you can transport the granular material up from one container and then pour it into another container higher up.

Yes your right there. We have been working for about a month now and of course they gave me this task and some hard ones to figure out. (Why me always me). Anyway you can move the substance (sand) by 1. connecting it to an axle as it spins the container moves upward. when it reaches the top it flips dumping it into another container. 2. Have the (sand) pour into a paddle wheel. It is more controlled this way. Just remember any substance that leaves the box would result in a penalty.

Google sand bucket elevator, grain elevator and gravel elevator.

I guess it would not be because it does say move and pour granular material from one container to another higher in the device. so i guess i would have to figure out a way to raise the material but i could not find and sand,gravel, or grain elevators.

I would question whether #1 is legal. If you move the container up and flip it to dump the stuff into another container, then it might not be correct by the letter of the rule. I am not sure, but it seems the granular material should be moved from the lower container. I am quite new to this so maybe I am reading too much into it.

Quick beginner question: can someone give me ideas on how to accomplish self-measured device for distance and IMA values of a lever or pulley device? Would putting a piece of paper with tick marks to indicate the length or distance from a reference point like in tape measuring be enough? If not, what are some of other ways of accomplishing this?
