Graphs for Static Force Systems
November 5th, 2022
1) An object of weight 20kn is supported from above by two cables, inclined at 40 degrees and 70 degrees to the horizontal. Find graphically the tensions in the cables.
2) Find graphically the forces f1 and f2 in the crane. The triangle is standing up with a 90 degree angle next to the wall on top, with f1 pointing towards it. The 60 degree angle is opposite to the 90 angle, with 2kn weight hanging from it. The 30 degree angle is at the bottom of the triangle, with f2 pointing towards the 60 degree angle.
