QUESTION 10 1.5 kg of a fluid is contained in a cylinder at an initial pressure of 30bar. The fluid is allowed
to expand reversibly behind a piston according to the law pv2= constant until the volume is
doubled. The fluid is then cooled reversibly at a constant pressure until the piston regains its
original position: heat is then supplied reversibly with the piston firmly locked in position until
the pressure rises to the original value of 30bar. Calculate the net workdone by the fluid, for an
initial volume of 0.05m3/kg

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

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.
