non calc physics problem help Application to the Russell traction system Any traction system can be analyzed by keeping in mind two things. First, the force applied is in the direction of the wire at the point where it is attached to the patient. Second, the force is equal to the weight hung on the wire. When a thigh bone or femur becomes fractured, a tential problem arises in the healing process. There is a tendency for the major leg muscles to pull together and misalign the two segments of the broken bone at the fracture point, thus sometimes causing shortening or ultimately a limp. To prevent this, traction is used to maintain tension and hold the adjoining structures in alignment. Figure 4.6 shows the Russell traction system which generates a force along the direction of the femur. The Russell traction apparatus is used for a fracture of a femur. This system is designed to elevate the upper leg at an angle of roughly 33 degrees above the horizontal. The mass of the leg is 4.00 kg. and the horizontal tension required to keep the leg stretched is 60.0 N. Find the values of masses m1 and m2. Draw some force diagrams for various objects or points in the mechanism. Which ones are useful toward solving the problem?)Explanation / Answer
