2) Stress and Strain - Strain
Engineering - Mechanics of Materials ·1. Deformation and Strain When an excessive stress is applied to the body of certain material, the shape of the body would be changed. It is called to Deformation. The deformation includes the case of yielding, necking, and rupture, etc., but in this chapter yielding is the principal subject. In a general sense, the deformation will not be uniform throughout...

1) Introductions for the heat and mass transfer
Engineering - Heat and Mass Transfer ·Why the mechanical engineer should know how the heat and mass is transferred? for mechanical engineers, it is essential for them to analyze:
- how the reaction between the mechanical components
- how the individual component or subsystem endures long for the given conditions
- how much mechanical power transmission occurs by heat and mass transfer
However, we don’t know exactly...
