eso204a - class summary

1
Class # 1 (27-07-2015) This class was an introduction to the field. We classified the area of mechanics into continuum and statistical mechanics, and discussed the concepts of the continuum hypothesis. Then we further classified continuum mechanics into solid and fluid mechanics. We discussed the differences between solids and fluids on the basis of their response to an applied stress. While solids respond with an equilibrium distortion, fluids respond with an equilibrium rate of distortion. Then the concept of viscosity was introduced. The expression of shear stress as a function of strain rate (Newton's law of viscosity) was derived. We then discussed about the rate processes. Finally we looked at some examples of applications. Class # 2 (29-07-2015) We started Chapter 2, the material on Fluid Statics. We obtained a mathematical treatment of Pascal's law - pressure at a point is the same in all directions. Then we derived the expression of pressure force on a fluid element obtaining the expression of the Law of Fluid Statics.

Class # 1 (27-07-2015) This class was an introduction to the field. We classified the area of mechanics into continuum and statistical mechanics, and discussed the concepts of the continuum hypothesis. Then we further classified continuum mechanics into solid and fluid mechanics. We discussed the differences between solids and fluids on the basis of their response to an applied stress. While solids respond with an equilibrium distortion, fluids respond with an equilibrium rate of distortion. Then the concept of viscosity was introduced. The expression of shear stress as a function of strain rate (Newton's law of viscosity) was derived. We then discussed about the rate processes. Finally we looked at some examples of applications. Class # 2 (29-07-2015) We started Chapter 2, the material on Fluid Statics. We obtained a mathematical treatment of Pascal's law - pressure at a point is the same in all directions. Then we derived the expression of pressure force on a fluid element obtaining the expression of the Law of Fluid Statics.
