Problem 529 | Friction

Problem 529
As shown in Fig. P-529, a homogeneous cylinder 2 m in diameter and weighing 12 kN is acted upon by a vertical force P. Determine the magnitude of P necessary to start the cylinder turning. Assume that μ = 0.30.

Hi sir. Goodmorning. Bakit po pala natanggal ung normal force sa horizontal surface when the cylinder turns due to force "P" and ung normal force sa may inclined surface ay hinde? I was thinking about the cylinder would be on the same spot po pa rin kasi if turned by a force "P" since angle of friction=tan-1(0.3)= 17° is lesser than the angle of the inclined plane.
