Find the equilibrium constant for the reaction called the water-gas reaction

H2+CO2<--->H2O+CO

at 1200 K

What is the effect of varying the number of samples and the frequency as in the steps (7) and (8), respectively?

(5) How the number of ripples is related to the number of harmonics in the synthesis of the periodic train of square pulse?

Why are the ripple absent in the synthesis of the periodic train of triangle pulse?

Why do you observe ripples in the synthesis of the periodic train of square pulse?

Draw a helical spring of circular wire and -in terms of load, dimensions, and material- express:

1. - max. shear stress,
2. - angular deflection,
3. - spring rate,
4. - energy stored,
5. - volume of spring wire,
6. - axial deflection, and
7. - length of spring wire.

Unpolarized light falls on two polarizing sheets placed one on top of the other. What must be the angle

between their transmission axis, if intensity of transmitted light by the analyzer is one third of that of

incident light?

A polarizer and analyzer are oriented so that the amount of transmitted light is maximum. Through what

possible angles should either be turned so that the intensity of transmitted light by the analyzer is reduced

to 75% and 25% of the maximum intensity

A 100 N force is applied at A as shown in figure below. Replace this force by a force-couple system at C and E.

Consider the steel column of a single storey building with the system of parallel forces as

shown in the Fig. Determine the magnitude of FA and FB such that the resultant force passes

through origin O of the given column. Use only vector approach to solve the unknowns

given.
