Strength Stiffness and Stability

Question 1

Define Strength

Answer 1

The Structure must carry the applied load without fracture

Question 2

Define Stiffness

Answer 2

The Structure must be stiff enough such that only Allowable Deformation Occurs

Question 3

Define Stability

Answer 3

The Structures ability to maintain its equilibrium and resist and external forces or loads.

Must not collapse through buckling

buckling - sudden change in component shape

Question 4

What is the Difference Between Yield Strength ,Tensile Strength and Ultimate Tensile Strength?

Answer 4

Yield Strength - Stress which a Material begins to deform plastically

Tensile Strength - Maximum Stress that a material can withstand before it Fractures

Ultimate Tensile Strength and Tensile Strength Mean the same thing
