Question: If the stress applied to a material is doubled, what happens to the strain if the material behaves elastically?

Options:

Correct Answer: It doubles

Solution:

According to Hooke\'s Law, if stress is doubled, strain also doubles for elastic materials.

If the stress applied to a material is doubled, what happens to the strain if the material behaves elastically?

If the stress applied to a material is doubled, what happens to the strain if the material behaves elastically?

Step 1: Understand what stress is. Stress is the force applied to a material divided by the area over which the force is applied.
Step 2: Understand what strain is. Strain is the deformation or change in shape of the material due to the applied stress.
Step 3: Learn about Hooke's Law. Hooke's Law states that, for elastic materials, the strain is directly proportional to the stress applied.
Step 4: If the stress is doubled, according to Hooke's Law, the strain will also double because they are proportional.
Step 5: Conclude that if the stress applied to the material is doubled, the strain will also double if the material behaves elastically.

Hooke's Law – Hooke's Law states that the strain in a material is directly proportional to the applied stress, provided the material remains within its elastic limit.
