- 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 combined weight of the leg and cast is W=180 N. The horizontal distance between points A and B where the cables are attached to the leg is L=100 cm and the vertical distance is d=5 cm. 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=30°. 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. (Write your result in N) Answerc) Find the angle α of cable 1 with the horizontal.

- Area moment is the measure of a body’s resistance to angular acceleration about a given axis. True of False? Please provide an explanation.Can anyone help me with this question. The Motor (J1=0.46 kg‐m2) is connected to a gearbox (J2 =0.27 kg‐m2 and J3=0.17 kg‐m2) by a steel shaft. The output of the gearbox is connected to a turbine (J4=0.37 kg‐m2 by a second steel shaft. The shafts are supported by bearings (not shown). The gearing in the gearbox is such that theta3=‐2.7theta2. Use Lagrange methods to determine the equation of motion for the system including the flexibility of the shafts, using variables of theta 1, theta 3, theta 4 based on changing theta 3.1: The cable AB prevents bar OA from rotating clockwise about O. if the cable tension is 750N, determine the n- and t component - as shown in fig 1
