  1. Bull! You Can’t Tip a Cow… Can you? Hannah Harris Megan Keller Toby Neal Sarabeth Royer

  2. What is cow Tipping? • Myth? Urban Legend? Or Bull Crap? • The mission, if you choose to accept it is to walk up to a sleeping cow, and tip it over • But, is this really possible?

  3. A Lesson on Animal Behavior • Cows actually don’t sleep standing • They are also very curious of new people, it is hard to “sneak up” on a cow • Even when resting, cows tend to face different directions so that someone in the herd will be covering each direction

  4. A cows line of vision is in the form of a semi-circle as shown in diagram • This would make it difficult to even approach a cow without making the cow react by moving away. • In order to tip a cow it would need to be still with not reaction. A Cows Line of Vision

  5. So Theoretically, is it Possible? • What is the force required to tip a cow? • Force = Mass X Acceleration • What does a typical cow weigh? • Newborn Calf: 80 lbs • Heifer: 800-1,000 lbs • Cow: 1,200-1,800 lbs • Bull: 1,700-2,100 • By the way, that is over a ton!

  6. Force= Ma • Mass ( 1,600 lbs) • Convert to kg (725.7 kg) • Acceleration = gravity • 9.8 m/s • (725.7)(9.8) = 7,111.86 • However, this be the force just to drop a cow…Not tip it

  7. An Unexpected Added Force • Cows lean- when pressure is applied to a cow, they will lean into it exerting an pressure back onto the object. • This makes the resistance of the cow and extra force to be reckoned with. • The force applied BY the cow would be equal to that being applied TOthe cow an the attempt of tipping.

  8. So How Much Force Can People Exert? • F = M X A • M = 150 pound person • (68.04 kg) • A = 6 miles per hour (average jogging speed) • (2.68 m/s) • F=MA • F=(150)(60) • F=(68.04)(2.68) • F=182.35 N • A 182.35 force is exerted by a person of 150 lbs jogging at 6 mph.

  9. Scientific Research • Margo Lillie • Doctor of zoology at the Universtiy of British Columbia • Concluded would require an exertion of 2,920 newtons • Would take at least 2 very strong people

  10. What new insight does this topic provide to you • Tipping a cow is not as easy as it sounds. • Be able to run faster than the bull is a must. • Maybe tractor tipping will be easier. • Being able to calculate the cow’s size and knowing your equations do come in handy When your just out having fun with your friends!!!!! • When it comes to “solving myths” do your research and know all the factors that are in play.
