The parallel axis theorem gives: $$ I = I_{\textrm{cm}} + md^2 \\ $$ where $I_{\textrm{cm}}$ is the moment of inertia about the object's center of mass, $m$ is the mass of the object, and $d$ is the distance from the center of mass of the object to the axis of rotation. You can also look at load acceleration and torque, where: $$ \tau = I\alpha \\ $$ Or, ...
