Question

question 43
the elastic region turns into the plastic region at the
ultimate yield point
ultimate failure point
elastic limit
plastic point
question 44
which of the following statements about the load - deformation curve is false
loads at curves in the elastic region do not cause permanent damage
the a - b segment of the curve represents the elastic region of the basic structure
the b - c segment of the curve represents the strength of the material in terms of absorbed energy
permanent deformation will occur if the load exceeds a certain point

Explanation:

For Question 43, the elastic - region transitions to the plastic region at the elastic limit. The ultimate yield point is related to maximum stress before failure in a different context, ultimate failure point is when the material breaks, and "plastic point" is not the standard term for this transition.
For Question 44, we analyze each option based on knowledge of load - deformation curves. Loads within the elastic region do not cause permanent damage. The initial linear portion represents the elastic region. And permanent deformation occurs when the load exceeds a certain point. The statement that is false needs to be identified by understanding the characteristics of the load - deformation curve.

Answer:

Question 43: elastic limit
Question 44: Please provide the full option texts for a definite answer.
