Question 1

(a) As an engineer who has just finished taking engineering materials course, your first task is to investigate the causes of an automobile accident. Your findings show that the right rear wheel has broken off at the axle. The axle is bent. The fracture surface reveals a Chevron pattern pointing toward the surface of the axle. Suggest a possible cause for the fracture and why?

(b)A cylindrical specimen of a hypothetical metal alloy is stressed in compression. If its original and final diameters are 30.00 and 30.04 mm, respectively, and its final length is 105.20 mm, compute its original length if the deformation is totally elastic. The elastic and shear moduli for this alloy are 65.5 and 25.4 GPa, respectively.

(b) A titanium pipe used to transport a corrosive material at 400°C is found to fail after several months. How would you determine the cause for the failure?
