Parallels question

Post by Lieficheep »

I'm new to science olympiad, and 2dv was sort of confusing to me. Does that limit it all the way to I can't have my circular-linear task pull a string to cause the pulley or the lever or is it just so that I cant have two different chains?

You can't have two different chains at any point. You can certainly have your circular to linear initiate your lever task--you just couldn't have your winch turning at the same time you were having another motor pull your lever, for example.

Double Duty Question

Post by Rose12 »

I'm new to this event (and to the whole of Science Olympiad). I have a question about the tasks. I'm sorry if this has already been asked or if this is a common knowledge question. I just couldn't find it on the site. :oops:

Can one actual event in the device count for two tasks?
For example, I plan to fill up a balloon with baking soda and create a vinegar/ baking soda reaction. Could this reaction count for both 3.f (inflate a balloon with a gas) AND 3.i (Initiate an enclosed chemical reaction that creates gas)?

I was actually just looking this same question up.
The answer is yes, you may.

Just be careful how you write it up in your TSL:
i. reaction creates gas
f. gas fills balloon

When one action is scored as two tasks. It's not allowed, with the exception of the gas from the chemical reaction filling up the balloon.

If I use the lever task to compress the first stage of my hydraulic task, the lever will be moving the same time the hydraulic task is moving. Does it count as a parallel task if the lever and the hydraulic system are moving at the same time, but the lever is causing the hydraulic system to move?
