1. For the chart below, calculate the maximum shear stress ( τ max ) and the maximum normal stress ( σ max ) at both a and b. 2. Consider the femur in figure 2, (length = 40 cm, inner radius 8 cm, outer radius 15 cm). If the femur will fail under tension of 60 MPa, what is the torque (moment) applied to one end of the femur required to fracture the femur? 3. For the diagram below describe the relationship between the total stress and total strain and the stresses and strains of each component of the model. 4. For the model above, if the model starts at rest and is then loaded with a constant stress, what is the strain at time zero and at infinite time in terms of the stress? 5. For the model above, if the model has been prestressed with a stress until equilibrium and then at time zero the stress is released what is the strain at time zero and at infinite time in terms of the original stress? 4,000 N 3,000 N 4cm each a b 10cm D 1 S 2 S 2 S 1
