An easy way I think would be to do a google call with another school at a different part of the world, then calculate the angle of the sun in the sky at the same time for both places. Obviously after doing some basic trigonometry, the results would only fit the round Earth model.
I never thought to search for average density. It was faulty logic to assume that an extremely compressed plasma core wouldn't increase the average density to more than that of a liquid or solid state. Might be the public misconception that stars are mainly bodies of "Gas" and "Plasma" and we...
How much smaller would the sun be if all it's hydrogen and helium turned to liquid?
I can't figure out how to calculate this. But I thought it would be fun to visualize how much smaller in size a frozen sun would be compared to it's gas/plasma state.
Anyone?
I'm an average joe here, trying to figure something out. Let's say I have a tube and a disk that travels from top to bottom pushing air kinda like a pump. Both tube ends are open so as air is pushed out of the bottom end, more air flows in through the top.
Here is my question: Does pushing air...
I'm building a simple 20:1 gearbox prototype with 2 compound gears in a row connecting to a third small gear at the end. My goal is to multiply the rotational speed of the small gear.
They are all engaged on a straight line. But for some reason they get stuck most of the time.
I'm trying to...
Hi everyone. This is my first post on the forums.
I wanted to ask your expertise on a project I'm working on.
I'm trying to design a setup where I rotate a ∏ shaped frame that has a 1kg load on the horizontal bar. The space between the frame should stay empty.
The length of the side rods...
