Knowing that the grain density of most sandstones is about 2.65 g/cm³, estimate the porosity of the core plug. b.

In the following set of questions, we will consider a mercury-in-glass thermometer. The tworeference points will be assigned 0.01◦C and 100◦C based on the triple point and boiling point ofwater. a) Remark on the the rationale for selecting references based on phenomena such as phase transi-tions. Identify any prospective issues or special considerations one might have with this approach? b) Draw a schematic of a mercury-in-glass thermometer. Define an appropriate set of universe,system, and surroundings and explain the functional operation of thermometer from a thermody-namic analysis perspective. In your response, you should describe how energy flows and influencesmatter. Is your system open or closed? What kind of boundary do you have? What kind ofapproximations (if any) do you make for the reliable determination of temperature based on yourdecomposition of universe, system, and environment?

(6) There are many kinds of polyethylene foam, each with different properties. The low density polyethylene foams (as seen in this video) are very flexible. Remember: in solid mechanics, "flexible" just means that in comparison to other materials, the material deforms quite a bit, relative to the stress. For torsion, the material property that relates to stiffness is the shear modulus (or modulus of rigidity), G. We'll say that G = 6 MPa. a) Complete the FBD. b) Compute the shear stress at Point B. c) Illustrate it on a stress element. d) Report the shear strain at B (in radians). e) Compute the rotation of the top plane. f) Compute arc length s.

stress and pore water pressure. 2- A soil profile consists of 10m of sand (Y=20 kN/m') over 3m of organic silt (Y=17KN/m, 0.5,0CR = 1,c, = 8 m2/year)over gravel. Initially, the water table is 2m below the ground surface and hydrostatic condition exists throughout the soil profile. Before constructing a structure on this site, the organic silt is preconsolidated by rapidly lowering the water table by 6m (to 8m below the ground surface) and simultaneously pumping from the gravel layer at such rate that the piezometric level in the gravel is lowered to the bottom of the organic silt. Compute settlement resulting from consolidation of the organic silt if the lowered ground water
