Homework Help: Inertial constant K

  1. Oct 23, 2006 #1
    I = kMr 2
    Where M is the mass of the flywheel, r its radius and k is its inertial constant.
    Can I calculate my own inertial constant( a sphere + 4 disks around the sphere)

    Thanks Help will be appreciated

    So in short im adding weight on the side of the ball .. as mass of the wieights is increased concentration of mass is distributed more... so I decreases. Im confused I dont understand the parallel axis theorm. An an increase in alpha would obviously mean an increase in spin velocity? Yes?
