Extracted text: : Sketch the complete and correct free-body diagram of each of the given structure and determine the number of unknowns. Assume that the weight of the structure is negligible unless otherwise mass is stated on the problem. 300 me Cable X0 mm 540 nun 30° (1) The homogeneous bar weighs 45 N. It is resting on rough surface (2) Bar under load Lis pinned at (3) Cylinder of mass 30 kg is supported by a cable at A and is resting on a friction surface at B. at A and smooth surtace at B. both ends.
