AI Thread Summary

To determine the gravitational pull on a 100-gram floating disk, one must first calculate the weight using the formula weight = mass x gravity, which equals approximately 0.98 Newtons on Earth. The opposing force required to counteract this gravitational pull must equal this weight to achieve levitation. The discussion emphasizes the need for a balance between the gravitational force and the force generated by the propulsors. While the initial request was to avoid complex math, understanding these basic principles is essential for solving the problem. Ultimately, the forces exerted on the surface area of the disk must be carefully calculated to ensure stability in a floating scenario.

For example, I have a floating disk,and there are four propulsors, the propulsors of this disk could generate unlimited opposing force (to the gravity). Let's say this disk weighs 100 grams and I want to find out the gravitational pull on this object and the opposing force required, how do I do it?(No crazy-math explanation please! =))

You can solve it, but first you must resort to using crazy math.

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
