Mechanical Engineering

Can you draw a Stress-Strain diagram with: aluminum, steel, hardened steel, plastics/ceremics? Any idea on which material to select with better performance in beam problem compared to aluminum?

Hint: How do aluminum and steel differ in yield strength and ultimate tensile strength?

Fun fact: This is one of the most common technical questions for mechanical engineers. You’ll often see variations of this question phrased in different ways (i.e. case studies, design trade-offs, etc.). Understanding fu…
