1. The problem statement, all variables and given/known data A stick of length 2L and of mass M spins with angular velocity ω around the axis perpendicular to the COM of the stick.It is rotating with making an angle Θ,with the axis parallel to Z axis.The COM has an initial velocity v=υ(to the y axis).Find it's precession radius R. 2. Relevant equations. Angular momentom L=IW Again L=mυR and τ=δL/δt 3. The attempt at a solution I figure out the torque τ and the change of angular momentum .then i find the gyroscopic relationship W=mgr/Iω Please help me to find the things out. Thanks.
