Innovation Day – Pulley Project

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.Barn elevator

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
