HW 4: $\underline{\text{ Russell’s traction mechanism }}$ Suppose research after years of using Russell's mechanism shows that the angle $F_{\text{femur }}$ makes with the horizontal should be 10 degrees (instead of 20) and the 40 degree angle at the knee should now be 42 degrees. Using your weight... a) Now what magnitude of weight (w) must be suspended from the end of the cable to maintain the leg in static equilibrium? b) Compute the tensile force applied to the thigh under these new conditions. c) The force place depicted in Fig. 9.9 has four sensors, one at each corner, that read the four vertical forces shown Use analysis of translational forces or summation of forces to determine the expression for $\mathrm{R}$ in terms of those four forces. The plate is in static equilib] Fig. 9.9 A square force plate with sides of length $?$ is loaded with resultant force $R$ and detects the vertical forces at each corner, $F_1?F_4$.
