An engineer was asked to estimate the elastic settlement of foundations at a project site. She/he used a Shelby Tube and collected a relatively undisturbed soil sample that measured 35 mm diameter and 70 mm long. She/he conducted a triaxial shear test applying major principal stress of 170 kPa (vertical), and minor principal stresses (horizontal) of 100 kPa, allowing drainage to measure reduction in the sample volume. The changed length of soil sample was 66.5 mm, and the reduction in volume was 3.72 ml (as measured by drainage from sample) Using the 3-D stress strain equation from your E MCH 213. Calculate (a) Modulus of elasticity and (b) Poisson's ratio.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

On a average work day more than work place firs are reorted

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.
