Now we have two new ones, bringing the grand total to 24 examples of the exact same thing. The new ones are:. .23. Centrifugal clutch.. .24. Baseball in your hand.. .. .Flight Safety: HAVE YOU CARRIED OUT MY EXPERIMENT? I shall atempt a final answer for you. I believe your example of the clutch is a great demonstration of centripetal (like the other 23). The flaw in your arguement is that the pads are not "flung outward". Despite 8 pages of why this is incorrect, you remain committed to this viewpoint. It is the crucial element to a centrifugal theory.. .. .The reality remains that the pads are not flung outwards. They attempt to move in a staight line but cannot because the drum is forcing them to turn. Turning equals a change in direction, which is a change in velocity, which requires the application of an acceleration, which can be considered a force. Acceleration is directional, therefore to turn, must accelerate, and accelerations act toward the change, therefore it must act toward the direction of turn. In a turn that continues into a complete circle, the centre of that circle is where the acceleration must act. IE the force is centripetal.. .. .There is no "flung outward". There is only the force required to turn the mass of the pads.. .. .The experiment I outlined is VERY SIMPLE, and takes less than 1 minute. PLEASE carry it out before thinking up another example.. . <img border="0" title="" alt="[Confused]" src="confused.gif" /> <img border="0" title="" alt="[Confused]" src="confused.gif" /> . .. .The experiment reposted:. .Everyone whom reads this thread need only carry out one simple experiment to see if the world’s physicists are correct in believing centripetal is real and centrifugal is not. Please carry this experiment out before posting again on this thread.. .. .Get a large easy to see object with some weight, such as a full soft drink can or water bottle. Go out side with a friend. Face a very obvious marker, such as a distant white building or even use your friend. Hold the object out at arms length from your body, DIRECTLY TO YOUR FRONT, so that as you turn your body, your arm stays straight out in front. Spin around. When you and your hand are exactly facing your marker, open your hand.. .. .PLEASE DO THIS BEFORE POSTING AGAIN ON THIS THREAD. <img border="0" title="" alt="[Smile]" src="smile.gif" /> <img border="0" title="" alt="[Smile]" src="smile.gif" />
