Consider the total hip joint prosthesis as shown in the figure. The geometric parameters of the prosthesis are such that \(L_1=40\) mm, \(L_2=60\) mm, \(\theta_1=45^\circ\), \(\theta_2=90^\circ\). Assume that, when standing symmetrically on both feet, a joint reaction force of \(400~\text{N}\) is acting vertically at the femoral head (point A) due to the body weight of the subject. Calculate the magnitude of the moment (in Nm) about point C. (Round off the answer to one decimal place.)
For a tissue with Young’s modulus of \(3.6\ \text{kPa}\) and Poisson’s ratio of \(0.2\), what is the value of its shear modulus (in kPa)? (Round off the answer to one decimal place.)
