Hello everyone. I come back here. Today we continue with another type of exercise. It is “If the load is increased beyond the point, the strain increases rapidly for even a small change in the stress” Let’s find the answer to this question together!
Question: If the load is increased beyond the point, the strain increases rapidly for even a small change in the stress.
Here is our full question:
If the load is increased beyond the point, the strain increases rapidly for even a small change in the stress.
(a) elastic point
(b) yield point
(c) plastic point
(d) fracture point
Answer
As you know: Yield point is the point, beyond which the wine starts showing increases in strain without any increase in stress.
So option B is correct answer
Relevent knowledge
Stress is a physical quantity that represents internal forces and is generated inside a deformed object due to the impact of external forces such as temperature, weight, etc.
It is often difficult to determine the yield precisely because of the many stress-strain curves represented by the actual material. In addition, there are several possible ways to determine yield:
Up to this stress level, stress is proportional to strain (Hooke’s law). Hence the stress-strain graph is a straight line and the slope will be equal to the elastic modulus of the material.
Conclusion
Thus, together, we have found the answer to the question “If the load is increased beyond the point, the strain increases rapidly for even a small change in the stress.”. If you have a better solution, please leave us a comment!
