Question
The spool has a mass of 150 kg and a radius of gyration of Kç = 240 mm about its centre of
mass G. The coefficients of static and kinetic friction between the rail and the spool are us =
0.2 and µk = 0.15, respectively. If a vertical force of P = 400N is applied to the cable,
determine the frictional force at the contact between the spool and the rail and whether the
spool slips.
