For the elastic body defined in Question 1 (below), define the boundary conditions in terms of displacement, assuming the boundary surface at the point in question has direction cosines with respect to x and y and z equal to l=0.8 and m=0.6 and n=0 . Consider the case when the change in volume is negligible.
Are all the compatibility equations satisfied for the Plane Stress conditions? If not, which equations are not satisfied? Explain the case for the Plane Strain conditions?
Question 1:
Write down the equilibrium equations for a three-dimensional isotropic material in terms of displacements. Assume that the material modulus of elasticity, Poisson ratio and density are, and that the body forces are due to the material weigh and the constant gravitational accelerations applied in z-direction.

The data below are comparing two different methods of measuring blood alcohol concentration. Test the hypothesis that these two methods differ, with the assumption that these data are not normally distributed, with an α = 0.01. Which test would be most appropriate? Provide critical value and calculated test statistic, and then state your conclusion.

In the following problems answer is given in bracket, I just want the steps how to get them:
(a). Calculate the % of each DRY product when coal is burned stoichiometrically in air. The mass analysis of the coal is: 80% C; 10% H2; 5% S; and 5% ash.(76.7%N, 22.5%CO2; 0.8% SO2)
(b). Find the air fuel ratio for stoichiometric combustion of Butane by volume. Calculate the percentage of carbon dioxide present in the DRY flue gas if 30% excess air is used. (30.95/1; 10.6%)
Make sure you cover both parts as Chegg Question allows at max 4 sub-parts. I want all the steps to get the correct answer.

Problem 2.2 Consider a production system consisting of three
Bernoulli
machines and a controller, which also obeys the Bernoulli
reliability model. This
production system is considered up if the controller and at least
two machines are
up. During each cycle, the controller is up with probability 0.8
and each machine
is up with probability 0.9. The controller and the machines fail
independently.
(a) Calculate the probability that the production system is
up.
(b) Assume that a second controller, identical to the first one, is
added to the
system, and the re-designed system is up if at least one controller
and two
machines are up. Calculate the probability that the re-designed
production
system is up.
(c) Explain the reason for the difference between the two numbers
you calculated.
