Why are diffracted beams formed only at incident beam angles that satisfy bragg's law, and not at other orientations? at what 20 value would the 220 peak for fcc nickel be formed if a cu kα1 x-rays beam was used?

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
