This is probably a fairly simple question, but I am struggling with it. My question is: Would you experience the effects of gravity if orbiting in a stable or circular orbit close to a black hole? This stems from my mental image of the International Space Station (ISS). There is obviously...

Thanks for the replies so far! Any additional input is appreciated! Thanks

No problem! I attached a picture. Please note that the sketches are not scale... F_b refers to the buoyancy force generated from the submerged portion of the wood, which is approximately 15.28 lbs for my design. For simplicity in my question, let's assume that the ramp is rigid and will not...

Hey guys, I designed a ramp to go from a boat dock into the water, allowing our dog to exit the water. I've done some rough calculations to estimate how large of a buoy I need underneath my ramp, and am missing only one variable at this point. I have accounted for the "live weight" which...

Thanks again for the thorough explanation! Went thought the math myself and everything is correct. As you mentioned, the equations are all independent of theta any which way you look at it. As a double check, looking at the moment about the center of mass quickly gives Fb = Fj, which also yields...

Thanks for the very in depth and thoughtful response. I'll digest tomorrow morning and will respond by tomorrow evening. At a first glance, the math checks out, but just not logically yet. Will look over in more detail and see if any questions come up. Thanks again for the response - would have...

Thanks for the reply! However, how can this be correct? Take for example, a person in the push-up position. The system is static, no work is being done, and we are simply looking at the pressure and force on the hands and feet of the person. In scenario 1, the person's feet are way below their...

Hey guys, I am building a small water ramp that will extend from a dock and into the water with a buoy at the end. I could probably just use trial and error, but thought it would be fun to make some rough calculations to help my design. This picture (http://imgur.com/a/bHYfG) shows the...
