Diffractions of X-rays

*Diffraction effect can be observed only if the spacing between the lines.
*The grating is of the order of magnitude of the wavelength of light used.
*The grating element is of the order of 10-6 m.
*The wavelength of x-ray is of the order of 1/1000th of the wavelength of visible light.
*The grating should have a spacing 1/1000th of the grating used in the visible region.
*Von Laue suggested that the crystal can be used for the diffraction of X-rays because the spacing between the atoms of a crystal are of the order 1Å.

“Pattern”- making, allowances and its types

“Pattern”- making, allowances and its types: Pattern: A pattern may be defined as a model of desired casting which when moulded in sand forms an impression called mould. The mould when filled with the molten metal forms casting after solidification of the poured metal. The quality and accuracy of casting depends upon the pattern making. The pattern may be made of wood, metal(cast iron, brass, aluminium and alloy steel.), plaster, plastics and wax. Pattern Allowances: A pattern is always made larger than the required size of the casting considering the various allowances. These are the allowances which are usually provided in a pattern. 1: shrinkage or contraction allowance: The various metals used for casting contract after solidification in the mould. Since the contraction is different for different materials, therefore it will also differ with the form or type of metal. 2: Draft allowance It is a taper which is given to all the vertical walls of the pattern for eas...

Calculate the maximum packing fraction of the unit cell volume that can be filled by hard spheres in the SC, BCC, FCC, Diamond and Hexagonal structures.  Which structure most efficiently fills space?  SC :  It is easy to determine that there is 1 lattice point per unit cell.  The maximum radius that a hard sphere can have is  , where  a  is the lattice constant.  When the radius is this value, then the spheres on the corners of the unit cell just touch each other.  Hence the packing fraction is: B.C.C :  It is easy to determine that there is 2 lattice points per unit cell.  The maximum radius that a hard sphere can have is  , where  a  is the lattice constant.  When the radius is this value, then the spheres on the corners of the unit cell just touch the body-centered sphere.  Hence the packing fraction is: F.C.C :  It is easy to d...

The Two-Wattmeter Method

Image
In a three phase, wye or delta three wire system, under balanced or unbalanced conditions, with any power factor, the two-wattmeter method is a practical and commonly used method of measuring total three phase power. A simplified circuit diagram of the two-wattmeter connections is shown in Fig.1. Figure1 is simplified in the sense that the ammeters, current transformers, selection switch, and polarity switch have been omitted. The polarities of the voltage and current connections to the wattmeters are significant. Note that the line in which the current is not measured, line “c”, is connected to the negative voltage terminal on both wattmeters. Figure 1: Connections for the two-wattmeter method. Notice that this is a three-wire system. The total power delivered to the load is given by Eq.1. P total = P 1 + P 2 (1) As indicated in Fig.1, each wattmeter measures a line current and a line to line voltage. The wattmeter reading indicates the product of line c...
