Pulley Investigation - OL
Purpose: This lab is to allow you to investigate different pulley designs and determine if any are suitable for lifting your coaster car onto the
stage.
In this lab, you will be lifting a model of a coaster car (your brick) to a height of .145m. This would simulate lifting a real coaster car onto the
stage.
You will be constructing multiple pulleys using the table below as your guide and answering the analysis questions.
1. What is the IMA?
2. Lift the brick .145m and record the input force.
3. Calculate the work.
4. What is the AMA?
5. Why does IMA not equal AMA?
6. How does this pulley system make work easier?
7. What’s the trade-off for using this pulley system?
1. What is the IMA?
2. Lift the brick .2m and record the input force.
3. Calculate the work.

Final analysis question: Which of these pulleys are the most reasonable for moving the coaster car onto the stage? Explain.
