Can You Proof This?

Hello everybody,

I cant proof the shear modulus of most materials with respect to the modulus of elasticity is less than half.

I knew that but I am very much weak in strength of materials. Thats why I am posting stupid questions.I know it is irritating,but i have to admit it that I am really very very weak in this chapter

Dear student,

The internet is a great resource for this type of education.

Here are a few to help get you started:

MatWeb: is a very valuable site. I use it all the time so that I don't have to bother the forum with trivial questions.

List of materials properties - Wikipedia, the free encyclopedia

Properties of Materials

MatWeb: Online Materials Information Resource

Properties of Materials - Science Games & Activities for Kids

THE PROPERTIES OF MATERIALS - Primary Resources

Try these sources first.

Did you consider the area?

Also I also think shear and elasticity are two different things so proving one with the other might be difficult.

See the "Relation among elastic constants" section in the following link: https://en.wikipedia.org/wiki/Young%27s_modulus

As most materials have a positive ν value the result is obvious.
