Mechanical advantage of a pulley

Lecturer Procedure

Steps to Follow

1. Attach 25-lb weight to the bottom of the lowest pulley.
2. Attach 5-lb barbell to the pulling cord.
3. Release.

Expected Result

5-lb barbell will lift 25-lb weight and keep it suspended with ease.

Note:

4.2 lbs should be sufficient to keep the weight suspended - the closest we have in stock is the 5-lb barbell.
