Final answer:
The rank of ultimate/tensile strength is cobalt chrome > titanium > stainless steel > cortical bone.
Step-by-step explanation:
The rank of ultimate/tensile strength for the given materials is:
- Cobalt chrome > Titanium > Stainless steel > Cortical bone
When comparing the ultimate/tensile strength of materials, cobalt chrome has the highest strength, followed by titanium, stainless steel, and cortical bone. Cobalt chrome is often used in applications that require high strength and resistance to corrosion, such as medical implants. Titanium and stainless steel also have good strength properties, but they are not as strong as cobalt chrome. Cortical bone, on the other hand, is a natural material found in the human body and has lower strength compared to the other materials mentioned.
