Mechanical Advantage of Common Tools
Introduction
This project we did In physics was to go out in our life and find different types of levers. We had to take a picture of it and measure the Distance In and Distance Out. Using the measurements I had to find the Ideal mechanical Advantage (IMA).
- Determine work done, given force & distance moved
- Determine amount of power required, given work & time Solve work and power problems
- Define work in terms of energy
- Distinguish between mechanical, potential, & kinetic energy
- Explain when grav. PE changes & not
- Describe how kinetic energy depends on speed
- State the law of conservation of energy
- Solve conservation of energy problems
- Describe the function of a lever, pulley, inclined plane, & wedge
- Give examples when mechanical advantage > 1 and < 1
- Explain why no machine can have efficiency of 100%
- Solve mechanical advantage & efficiency problems
Summary
As I went and searched for my three machines it was easier the i had thought. There are so many simple machines in my everyday life. As you can see in the File link above those are some of the levers I had found.
