the spool has a larger radius ?=0,17 and an inner radius ?=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
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 ?, the spool has a larger radius ?=0,17 and an inner radius ?=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.
