Consider the total hip joint prosthesis as shown in the figure. The geometric parameters of the prosthesis are such that L₁=40 mm, L₂=60 mm, θ₁=45°, θ₂=90°. Assume that, when standing symmetrically on both feet, a joint reaction force of 400 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.)
