Activity:
Real Life Question:
Is there a fixed ratio between stress and strain acting on a body?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Elastic Moduli | Ratio between stress and strain on a material. |
| Strain | When there is a strain, there ought to be some change in dimension of the body. The change in dimension by original dimension is called stress. |
| Stress | A deforming force on a body causes a restoring force from the body. This restoring force per unit area is stress. |

What you learn in Theory:
That the ratio
between the stress applied on the body to the strain produced because of it is
constant.
What you learn in Practice:
The Modulus of
Elasticity tells us about the tendency of the body to get deformed elastically.
