PASSAGE
A spool consists of an inner hub of radius rr and an outer flange of radius RR (R>rR > r). The total mass is mm and the moment of inertia about the center of mass is IGI_G. A horizontal cord is wrapped around the inner hub and pulled with force PP horizontally to the right. The spool rests on a horizontal surface. The contact between the spool and surface provides a friction force ff.
Applying ΣMG=IGα\Sigma M_G = I_G \alpha about the center of the spool, and assuming the spool rolls without slipping, which equation is correct (taking clockwise as positive α\alpha)?
