That upper partical is not half inside and upside but that above that there is no particle which can pull that particle so the net downward force acts on that particle and the whole surface behaves like an stretched membrane and the phnemenon is surface tension

Kritika Trehan 8 years, 4 months ago

As the term implies, "Modulus of Elasticity” relates to the elasticity or "flexibility" of a material. The value of modulus of elasticity is very much significant relating to deflection of certain materials used in the construction industry. Take for example the general E value of mild carbon steel is about 200 GPA comPAred to about 70 GPA for aluminum. This simply translate that aluminum is 3 times flexible than steel.

It indicates that how a material will behave under the application of load. An elactic material has more tensile strength and it can be stretched to a greater extent like steel. So basically good to resist tension at the time of bending.
