The ISS is major accomplishment for NASA (US), ESA (Europe), JAXA (Japan) CSA (Canada) and all the countries involved (16 in all). The space station is just over 72 m long by 108 m wide and 20 m high
An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed. Each cup is attached to the end of a horizontal arm, each of which is mounted on a central axis, like spokes on a wheel. When wind pushes into the cups, they rotate the axis. The faster the wind, the faster the cups spin the axis.
What kind of power would you need to overcome this obstacle? Why is this such a difficult thing to do? Well, a ninja trying to climb this ladder not only has to do something like a pull-up (no easy feat) he has to end the pull-up with enough vertical velocity so that he can be “airborne” long enough for him to move the bar to the next level. Really, this is the part that makes it tough and this is the part that I want to calculate the power for. Let’s go.
