I have chosen to make a barn elevator.
Scientific Process
What pulley system does your choice include: I used a Fixed Pulley system for my project.
Explain how that system works: You have to roll the dowel while the dowel rolls up the elevator.
Scientific Process- Hypothesis
What is your hypothesis (what will happen when you pulley your pulley machine): You will pull the dowel while the dowel rolls up the strings which is pulling up the elevator.
Scientific Process- Conclusion
My Hypothesis was correct.
I thought if I put 1 string on the left side same on the right side it would balance the elevator while I pull it up
