The state of strain at the point has components of ϵx = 200(10−6), ϵy = -120(10^−6) and γxy = -100 (10−6).

1) Use the strain-transformation equations to determine the in-plane principal strains.

ϵ1,,ϵ2

2) Specify the orientation of the element.

3)Determine the maximum in-plane shear strain.

4) Specify the orientation of the element.

(θs)1,(θs)2

5) Determine average normal strain. ϵavg

You have been given 6 new strains of Bacillus sp. recently isolated from a mine site. In order to gain some understanding about these strains you set up growth experiments to determine their growth over 24 hours. A spread plate viable cell count technique was utilised. The bacteria were grown at 37oC in a nutrient broth medium and samples were taken after 24 hrs. Each sample was serially diluted from 10-1 to 10-4 and 100 µl aliquots were plated onto...

The fuel element of a nuclear reactor is in the shape of a plane wall of thickness L = 20 mm. It is being maintained at a constant temperature of 250ºC on both of its surfaces. At normal operating power, heat is generated uniformly within the element at a volumetric rate of q = 107 W/m3. A departure from the steady-state conditions associated with normal operation will occur if there is a change in the generation rate. Consider a sudden...

Anne faces an uncertain World with two possible states, good and bad. In the good state she has money holding MG and in the bad state, she has money holdings MB. We will write the money bundle M = (MG,MB). The good state is realized with probability ? and the bad state is realized with probability 1 - (pi). Anne’s preferences are characterized by expected utility function, U(M)=(pi)(MG)^(1/2) + (1-pi)(MB)^(1/2). Let pi=3/4. 1) How does Anne rank the following three...
