Determine the shaft work head delivered by the pump if the working fluid is water at 30 oC and the pressure above the liquid surface inside the tank is 2 atm. The lengths H1 and H2 are given on the Canvas exam page.

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

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
