• The deformation and flow of materials

• The taste of food

What does the yield point in rheology indicate?

• The point where a material behaves like a solid

• The point where a material behaves like a liquid

• The lowest shear-stress value above which a material behaves like a fluid

• The highest shear-stress value below which a material behaves like a solid

What does the storage modulus represent in the complex shear modulus?

• The viscous portion

• The elastic portion

• The plastic portion

• The fluid portion
