[amp_mcq option1=”Stiffness” option2=”Proof resilience” option3=”Proof stress” option4=”Proof load” correct=”option2″]
The correct answer is: B. Proof resilience
Proof resilience is the strain energy stored in a spring when subjected to the greatest load without being permanently distorted. It is a measure of the spring’s ability to absorb energy without being damaged.
Stiffness is the resistance of an object to deformation under an applied force. It is a measure of how difficult it is to bend, stretch, or compress an object.
Proof stress is the maximum stress that a material can withstand without permanent deformation. It is a measure of the material’s strength.
Proof load is the load that causes a material to reach its proof stress. It is a measure of the material’s load-bearing capacity.
