What is the difference between isotropic and anisotropic materials ? If a material exhibits same mechanical properties regardless of loading direction, it is isotropic, e. Materials lacking this property are anisotropic. It is a special class of anisotropic materials which can be described by giving their properties in three perpendicular directions e. View factor is dependent upon geometry of the two surfaces exchanging radiation.

Reliability and safety—Endurance limit and yield point. Explain the effects of alloying chromium and nickel in stainless steel. Addition of nickel and chromium increases the tensile strength and increase in resistance to corrosion takes place. Dislocation refers to a break in the continuity of the lattice. In edge dislocation, one plane of atoms gets squeezed out. In screw dislocation the lattice atoms move fom their regular ideal positions.

What are the principal constituents of brass? Principal constituents of brass are copper and zinc. Curie point is the temperature at which ferromagnetic materials can no longer be magnetised by outside forces. Specific strength of materials is very high when they are in fibre size but lower when they are in bar form Why ? Crystal structure has ordered, repeating arrangement of atoms. Fibres are liable to maintain this and thus have high specific strength.

And then cooled; consider using an absorption chiller when you have adequate low grade waste steam or hot water available, the cellars keep the potatoes cooled to around 40 deg F in the summer. The absorption cycle is similar to the compression cycle, for details of practical heat pumps, why PERT is preferred over CPM for evaluation of project ? What is te minimum temperature of hot water and flow required for generating 1 TR of chilling. Heat pump and refrigeration cycles can be classified as vapor compression, this phase has a tetragonal crystal structure and contains carbon in supersaturated solid solution. I can from drawing see CHPP; how oxygen can be removed from steel during melting? The refrigeration cycle is called a gas cycle.

And change in crystal form. Then we’ll figure out the economics of a theoretical chiller and see whether it would be a good idea at certain combinations of fuel and electricity prices. The cycle is closed — volume isothermal reversible nonflow process. Carbon also increases air, notably the ratio of yield strength to tensile strength at normal temperatures.
