Tubular Tires
Tubular Tires
help with physics please?
A projected space station consists of a circular tube that will rotate about its center (like a tubular bicycle tire) as shown in the figure . The circle formed by the tube has a diameter of about 1.1km
what must be the rotation speed (revolutions per day) if an effect equal to gravity at the surface of the earth (1.0g) is to be felt?
Fc=(m)9.8m/s^2
Fc=(m)9.8m/s^2=(mv^2)/r
9.8m/s^2=(v^2)/r=(v^2)/550m
v^2=5390m^2/s^2
v=93.4m/s
The circumference of the orbit is 1100*pi meters, or 3455m
at 93.4 m/s, one revolution would take 3455m/(93.4m/s)=37s
There are 86,400 seconds in a day, so one day would contain (86400s)/(37s/revolution)= 2335 revolutions
it seems I did the math incorrectly when I was finding the velocity..all of the concepts are sound, though, you should be able to work it out
