"Big wheel" in space initial angular speed is zero. The low earth orbit "big wheel" radius is R=100m and its moment of inertia is l=3.00x1010kgm2. The "big wheel" utilizes gravitational torquing, discussed in lecture, with green energy powered robot arm and two diametrically oppositely positioned masses m=50.0 ton each that are always aligned at 450 angle in respect to nadir. Eventually, the "big wheel" reaches required angular speed providing sense of artificial Earth's gravity on its rim. How long it takes to attain the right angular speed?
