Question

which deformation is a result of the same force applied over a long period of time? a) elastic stretch b) plastic stretch c) both of the above d) none of the above

Explanation:

Elastic stretch occurs when a force is applied and the material returns to its original shape when the force is removed. Plastic stretch happens when a force is applied over a long - term or exceeds the elastic limit, causing permanent deformation. When a force is applied over a long period of time, plastic stretch is more likely to occur as the material may exceed its elastic limit under the continuous influence of the force. Elastic stretch is more associated with short - term, reversible force application.

Answer:

b) Plastic Stretch
