You are selecting a material for use in an orthopedic implant. You anticipate that the peak longitudinal loading on the implant would be 50 kN.  The implant is cylindrical with a length of 10 cm and a cross-sectional area of 4 cm2.  The material is made of titanium with a reported value of Young’s elastic modulus = 100 GPa (1 GPa = 109 Pa). (12 points)   Determine: a) The peak stress in longitudinal direction b) The strain in the material when the peak stress is applied. c) The change in length of the specimen when the peak load is applied. Please clearly label your numeric answers for parts a, b, and c in the text box below.

For each of the following four knee positions (A, B, C, and D), there are two weight vectors (vector 1, indicating the weight of the leg, and vector 2, indicating the weight of an external weight attached to the ankle). State the angle of the each vector’s moment arm relative to the thigh segment (i.e., the upper portion of the leg that is proximal to the knee joint), such that perpendicular to the thigh would be 90
