1. ### Calculating acceleration on different gears in vehicle

I really find it difficult to help people who act like they know more than centuries of science as opposed to people who want to try to understand where their understanding is flawed. If they are not looking for the flaws in their understanding they will continue to make the same mistaken...
2. ### Calculating acceleration on different gears in vehicle

torque is not force. Unit of force is Newton. Unit of torque is Newton-Meter. Torque is force times distance. So your leverage needs to be part of your acceleration calculation.
3. ### Q: How to measure the force of impact of 100,000 lbs/sq inch or more?

Is 100,000 lbs/sq-in really the right way to think about it? For example if you pounded on a 1 ft diameter post, the thing you are trying to measure wouldn't be any different than pounding a 6 in diameter post. I think what you really want to know is the momentum transferred to the post. The...
4. ### What happens in a particle accelerator?

sorry Drakkith --- your answer was good, and I always appreciate your effort to clarify. Obviously the poster did also.
5. ### What happens in a particle accelerator?

Nobody has even bothered to try to describe the "pure energy" given off by proton annihilation. Instead a simple question and incorrect declarative statement is met with childlike derision. Unfortunate, and certainly unprofessional. Seems like a problem to me. As for an attempt at an...
6. ### Water column and pressure

I calculated 408 inches. But thought I must be missing something. EDIT: Ahhh --- here it is http://www.simplepump.com/OUR-PUMPS/Pump-System.html One lifting element at the bottom can "theoretically" do the job.
7. ### Water column and pressure

Sorry, I must have skimmed right over that post. I know nothing about this. This link seems to say you can pull it from 325 feet. http://www.simplepump.com/OUR-PUMPS/Hand-Operated.html
8. ### Water column and pressure

A lot of talk but no one has answered the simple question. How much force is required to pump water up from 800 ft. Frame the scenario any way you want to allow an answer to that question. Assume a 800ft water table.
9. ### Using sound for estimations

Too many variables. All you have is a sound, and know nothing of distance or velocity. You can't determine ANYTHING from the sound unless you know EXACTLY what the sound consists of. Then you can determine the relative velocity from the frequency, and then, making assumptions about...
