Question

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?

Answer 1

Answer is given below

Explanation:

• Evidence shows that the axle was not broken before the accident, while the clumsy axle meant that the wheel was still attached when the load was applied.
• This indicates that the Chevron prototype wheel suffered a severe impact shock, which caused the failure of the transmission to the axle. Preliminary evidence suggests that the driver lost control and crashed.
• Further examination of the surface, microstructure and structure and characteristics of the fracture can be modified if the axle is properly prepared
