A solid cylinder of mass \( m \) is kept in balance on a fixed incline of angle \( \alpha=37^{\circ} \) with the help of a thread fastened to its jacket. The cylinder does not slip.
P
W
In what direction should the thread be pulled to minimise the force required to hold the cylinder? What is the magnitude of this force?
(1) \( \frac{3 m g}{10} \) parallel to incline (2) Vertical \( \frac{3 m g}{8} \)
(3) Horizontal \( \frac{m g}{5} \)
(4) None of these
