Braced cuts

The braced cut is a method of providing lateral support to the soil in foundation trenches, to prevent the trenches from deformation by the caving in of soil and resisting it from moving laterally. During shallow excavation in firm soil, generally, slopes are provided to resist the caving in of soil. During shallow excavation in soft soil and deep excavation, the chances of caving in of soil increase. Hence, it becomes necessary to make a provision to resist the deformation of trenches due to caving in of soil. The braced cut is the method used for such conditions. The excavation using braced cuts is a bit uneconomical as compared to the traditional open-cut excavation method but provides better safety than the cut excavation method.

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.
