(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 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?
