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.

in the system shown, the bar AB can withstand a tension of 4.90 kN, and a compression of 2.53 kN; the spring constant k is 2.85 kN / m, the spring's undeformed length is 0.433 m, the mass of W is 365 kg, and the force P makes an angle of 60 ° with the horizontal. Calculate the stretched length of the spring and the magnitude of the force P so that:- The bar fails due to tension- The bar fails due to compression NOTE 1: For the direction of the force P do not be guided by the drawing. The force P can point in any direction (all 4 quadrants) as long as it maintains the indicated angle with respect to the horizontal.
