What is a Spatial Force System? 2.Three-dimensional equilibrium problems for a rigid body can be solved using what procedure?A former Mechanics student wants to weigh himself but only has a scale A limited to 400 N and a small spring dynamometer B that measures up to 80 N. With the assembly shown, he discovers that, by pulling the rope so that B points to 76 N , the scale reads 268 N. What are its correct weight W and mass m? (see img)A horizontal board weighing Wb = 600 N is hinged to a vertical wall. A personweighing Wp = 400 N stands at the end of the board 5 m from the wall. A rope is attached to theboard at a point 3 m from the wall and makes an angle of θ = 40° with theboard. Determine the tension (T) in the rope

- The figure shows the Russel fracture traction device and a mechanical model of the leg. The leg is held in balance in the position indicated by the two weights attached to the two cables. The total weight of the leg and the cast is W=250 N. The distance between the points A and B where the cables are attached to the leg is given as L=100 cm and the angle of the leg with the horizontal is γ=6°. Point C is the center of gravity of the cast and leg at three quarters of the L measured from point A (3L/4= 75 cm). The angle that cable 2 makes with the horizontal is measured as β=40°. Accordingly, in order for the leg to remain in balance in the shown position; a) Find the tensile force T1 in cable 1. (Write your result in N) Answerb) Find the tensile force T2 in cable 2.
