Question

question 6
a twisting force causes

question 7
the elastic region turns into the plastic region at the
o elastic limit
o plastic point
o ultimate yield point
o ultimate failure point

question 8
grade one sprains are the most serious.
o true
o false

Explanation:

For Question 6: A twisting force causes torsion, which is a form - of deformation in materials.
For Question 7: The elastic region turns into the plastic region at the elastic limit. Beyond this point, the material will not return to its original shape after the load is removed.
For Question 8: Grade one sprains are not the most serious. Higher - grade sprains (like grade three) are more severe with more extensive damage to ligaments. So the answer is False.

Answer:

Question 6: Torsion
Question 7: elastic limit
Question 8: False
