Question

According to the picture, the traction allows the leg to be suspended in a state of what? (Please explain)
A. Constant velocity B. Constant acceleration C. Equilibrium The force of the blow is so great that the player's femur is broken. The player is required to spend some time in traction. The Russell system of traction, which was used, is diagramed in Figure 3. Figure 3 The forces S, Q, and P are all equal in magnitude and equal in magnitude to the tension in the cord. The vector sum or resultant of the forces S, Q, and P is the force pulling on the femur. With respect to the horizontal, S makes an angle of 20° below, Q an angle of 30° above, and P an angle of 45° above.

Explanation / Answer

The Russell Traction System is used to immobilize a fractured femur (the thigh bone), doctors often utilize the Russell traction system illustrated in the figure. Notice that one force is applied directly to the knee, ,while two other forces, and are applied to the foot. The latter two forces combine to give a force that is transmitted through the lower leg to the knee. The result is that the knee experiences the total force . Therefore the traction allows the leg to be suspended in a state of equilibrium
