Tornado Tracks - Destruction power

I need webpage content that describes or defines the destruction power of the various tornado ratings. I believe tornados are rated as F1, F2, F3, etc... but you should do the research and provide me with accurate information. The content needs to include the different ratings or levels of tornados including wind speeds and possible destruction power. Compare the various wind speeds to some common factors for example what wind speed of 75 MPH could do such as pull 18 inch oak trees out of the ground or lift a 3000 pound car or truck. I do not know what these factors are and am looking for you to provide the facts and comparisons. The content needs to include the phrases "Tornado Tracks", "Tornado Destruction Power", "Tornado Power", and "Wind Forces" as often as possible.
