A sand specimen is isotropically consolidated in a triaxial test apparatus to 420 kPa and then sheared with the drainage valve open. At failure, the deviator stress is 1046 kPa. a) Determine the major and minor principal stresses at failure and the effective internal friction angle (assume c'

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
