Question

The shear modulus measures the resistance to change in shape. can someone plz explain this its earth science. I dont get it..

Answer 1

"The shear modulus describes the material's response to shearing strains."

Are you looking for a mathematical description? Shearing strains are changes in angles of planes in a given material. Shear stress is the force per unit of area on the material. The ratio of the two is the shear modulus.

Answer 2

thx man

Answer 3

Note that the ratio, the force per unit area, versus how much the angles of planes change in the material, is an indirect marker of resistance. Imagine I put force on a material, and the angles changed very little; thus, the ratio is high, and the modulus--resistance--is high.

Answer 4

this question is confusing. The moment magnitude of an earthquake depends on all of the following except __.
1.the area of the fault break
2.the rigidity of the fault
3.the slip on the fault
4.the type of faulting

Answer 5

I'm sorry, I've never taken an Earth science class. Shear stress was just brought up in Modern Physics.

Answer 6

oh ok so for the first question then the answer is the resistance in shape because of the stress of the plates angels

Answer 7

angles
