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...
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.
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...
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...
I calculated 408 inches. But thought I must be missing something.

One lifting element at the bottom can "theoretically" do the job.
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.

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.
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...
