Thank you. That is where I went wrong. I knew I needed to subtract and every time I tried to get my math to double check i was not working for me. I was not squaring the numbers before subtracting them. It makes perfect sense now.
My radius is 500m; I wrote it in the original problem but I...
I don't think I'm explaining why this is so challenging to me (other than the fact that I've been out of school for 30 years).
I want the person to "feel" gravity as being perfectly downward to the floor of the room, even though the floor is truly angled due to the bank of the curve.
So...
Homework Statement
A train on the planet surface of Mars is traveling along a banked track shaped as large circle with a radius of 500m.
Q. Assuming Mars gravity is 3.8m/s^{2} what Velocity v must the Martian train travel to simulate a total artificial gravity equal to Earth's...
I am just powering a small electronics board that sleeps most of the time and it generally only wakes up for about 2 minutes per day, unless it's time to change over to/from daylight savings; so I meant that my total energy needs are AAA battery size.
Although my needs are small I'm able to...
Nickel-Iron batteries are making a comeback in the renewable-energy industry. My personal interest happens to be for wind generator/solar power energy storage and also for a pendulum gear-driven clock design that I am working on where I need a minute amount of stored power to operate a small...
The pendulum will swing mechanically from weights that will be reset manually, so the kinetic energy is endless as long as the owner cares for it.
I'm going to make a new post and ask for a specific request on how to make a Nickel-Iron battery last the longest--this seems like my best choice...
It seem that the Silicon-Air battery has some promise in the somewhat near future. I am hoping that i can use my low energy needs to my advantage, especially since I have the needs of a small AAA battery with size capacity afforded to a golf to a golf cart.
So I want to see if I can use this...
I want to make an heirloom mechanical pendulum clock that is very tradition in design and yet will accurately work for centuries—and so I want to micro adjust the pendulum amplitude automatically and that requires some electricity, not very much electricity, but it will take some small amount of...
