Challenge #2: Pulley System
Think: We are going to make a new simple machine, a pulley system. We don't know what the instructions are and we don't know if we have to move blocks up or down. I think we are just going to do the original build today
Think: We made a lever for our pulley system. It worked sometimes but after some editing, we got it to work every time. Today we will test it with the three blocks and lift it over a least 3". After we test it we have 2 options, if we fail then we have to edit it more, if we dont fail then we start callenge #3, The Lever.
Do:Well, we failed. So we will have to do a lot of work. Tomorrow we will make a cage to keep the blocks on and so they don't fall off.
Think: So yesterday we failed, because the wheels werent strong enough to hold the wheight of the three blocks. So today we are going to try and build a sort of cage so then we can actually hold the blocks but we are taking the wheels out to keep the blocks on. Then we have to see about the crank because of the cage it might need a different crank. We'll see what happens.
Do: The cage did not work, because we tied the string onto the wrong side. So tomorrow we are going to see if we can get the blocks up to 3" high.
Think: yesterday did not go so well, we failed getting the three blocks up 3". Probably because it was too heavy. Today i think we will finish the pulley system, I hope. We will change the weight of both sides so it is equal and one side won't weigh more than the other.
Do: we got the pulley to work and lift like 10" off the table
