Please reply as soon as posible, thanks! I don´t have much time:( Static Problem: The spool shown in the figure has a weight of WAB = 27,50 N, and its center of gravity is located at its geometric center O, the spool has a larger radius R=0,17 and an inner radius r=0,13, and it has a coiled rope. Block C has a uniform weight WC= 60 N. Consider the friction between block C and the top of the spool at A, between the spool and the surface at point B and between the rope and pulley D, the friction coefficients are respectively: μs@A=0,30, μs@B =0,45 and μs@D=0,35. The chord is parallel to the plane. Carry out: a) The free-body diagrams of the block and the reel. b) The calculation of the maximum value of P that can be applied without losing the equilibrium of the system.
