In other words a cant resist a shear stress. At least ideally, it cant. In reality, some small resistance does exist for those s that are liquids. A shear stress is a force per unit area applied tangentially to material surface or layer. A normal stress, on the other hand, is applied perpendicularly (or normal) to a surface or layer. a) rope b) crystal c) fluid d) solid e) ice 015 qmult 00110 1 1 3 easy memory: liquids and gases 2. Fluids are either: a) solids or liquids. b) solids or gases. c) liquids or gases. d) crystals or gases. e) ices or metals. 015 qmult 00120 1 4 5 easy deducto-memory: solids defined 3. Lets play Jeopardy ! For $100, the answer is: They are materials in which the atoms or molecules are rigidly (but not perfectly rigidly) bonded together by chemical bonds. They resist shear and normal stresses. The atoms or molecules are essentially touching in theseresist shear and normal stresses....
