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). Q1H: Provide a brief rationale based on calculations used to support your answer. That is, how would you explain the behavior of the "new alloy" material to your design team?

An applied load of some magnitude F produces a 7x10-³ mm change in diameter (see figure below, original shape is blue, elongated shape is unshaded). Q1E: Of those two materials (F75 CoCr alloy (as cast) and F90 CoCr alloy (hot forged)), which materials would you select to assure that the deformation is entirely elastic (No yield!)?

12.44 A three-point bending test is performed on a O spinel (MgAl,O4) specimen having a rectangular cross section of height d = 3.8 mm (0.15 in.) and width b = 9 mm (0.35 in.); the distance between support points is 25 mm (1.0 in.). (a) Compute the flexural strength if the load at fracture is 350 N (80 lb;). (b) The point of maximum deflection Ay occurs at the center of the specimen and is described by FL³ Ay = (12.11) 48EI where E is the modulus of elasticity and I is the cross-sectional moment of inertia. Compute Ay at a load of 310 N (70 lb¡).

A three-point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 5.6 mm; the specimen fractured at a load of 4280 N when the distance between support points was 43 mm. Another test is to be performed on a specimen of this same material, but one that has a square cross section of 18 mm in length on each edge. At what load would you expect this specimen to fracture if the support point separation is maintained at 43 mm? Ff= N
