I thought it would be thrown free at first too, but then I realized that since the station at the end is in geostationary orbit, the real force holding it in place is gravity, not the tether. If the tether is then cut, it wouldn't stop the force holding the station in place.

@Skeptic2 -> I am pretty sure that the length wouldn't be an inhibiting factor, as you could just increase the mass and have the same effect. @filip -> It would make sense to put some net force on the tether to increase stability, but it should also be possible to balance it perfectly in an...

Was anyone else struck by the irony of the topic title?

Suppose the classic elevator is created, affixed to the Earth somewhere on the equator. The elevator would be perfectly balanced so that there would be no net force i.e. the centrifugal force of the string and end station would equal the force of gravity. What would happen if the cord was...

Im going to assume that you know how tiny the difference in weight is going to be from the top of the building to the bottom. The best way to calculate the force of gravity is to use Newtons approximation G*(g1*g2)/r^2. It looks like your also calculating the centrifugal force due to the...

Since the chili is going to melt from the outside in, the best way to decrease the melt time is to increase the surface area i.e. break it up into smaller frozen chunks.

To calculate the weight of the gas displaced, you have to use the percent mixture of nitrogen, oxygen, CO2 ect. I am pretty sure that at STP the ratio is 24 liters per one mole of gas particles. For calculating the rate of assent, since you already know the weight of the craft and the lift...
