Consolidated drained triaxial tests were conducted on three identical soil specimens with different cell pressures. At the failure the deviatoric stresses were measured as follows. Specimen No: 1 2 3 Cell Pressure (kPa): 50 100 150 Deviator stress at failure (kPa): 90 125 170 (i) Draw the necessary plots and determine the shear strength parameter(s) of the soil. (ii) Comment whether the soil is normally consolidated or overconsolidated.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

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
