You wish to lift a 12,000 lb stone by a vertical distance of 15 ft. Unfortunately, you can only generate a maximum pushing force of 2,000 lb.
What is the amount of work you must input
in order to move the stone?
What is the actual mechanical advantage (AMA) required by a machine to complete the work
You build a ramp to create the ideal mechanical advantage. What is the length of the ramp in feet?
