Mini-Quiz FEB 25th

Design a complex machine that meets the following specifications:

Ability to lift 20g of mass at least 20 cm from a flat surface

Uses only weights/gravity ass its energy source Uses at least 2 simple machines Is free standing

The “winning” machine will lift the mass using the least amount of weight as an input force.

Formula for machine “lifting points” =

work (mass * 9.8 * distance lifted)/input force (mass of weights * 9.8)

Complex machine challenge

Warm up: A 5 N force is used to moved an object 2 meters. How much work is needed to complete this task?

Exit: How much power is needed if the task in the warm up took 1 second to complete?

What if it takes 4 seconds to complete?
