# P7.13 The horizontal force P acts on the rim of the homogeneous cylinder ofradius R and weight W. Determine the smallest coefficient of static friction thatenables the cylinder to start rolling up the 30° incline30°Fig. P7.13 A30°6.4 in450Fig. P7.237.23 The 40-lb spool is suspended from the hanger GA and rests against a ver-tical wall. The center of gravity of the spool is at G and the weight of the hangeris negligible. The wire wound around the hub of the spool is extracted by pullingits end with the force P. If the coefficient of static friction between the spool andthe wall is 0.25, determine the smallest P that will extract the wire.9 in.
