... Question 1 You are working on a design team at a small orthopaedic firm. You have been asked to select a cobalt- chrome-molybdenum (CoCr) material that will not experience plastic deformation under a specific mechanical test, as follows... A tensile stress is applied along the long axis of a solid cylindrical rod that has a diameter of 10 mm. An applied load of some magnitude F produces a 7x10³ mm change in diameter (see figure below, original shape is blue, elongated shape is unshaded). Q1F: How would the "new alloy" material (with different properties as shown below) behave, assuming it has the same initial diameter (10mm) and applied load (F) in the tensile test? That is, would it experience plastic deformation (yield) under the conditions of this problem?
