A 30 m vertical column of fluid (density 1878 kg/m3 ) is located where g= 9.65 m/s2 .find the pressure at the base of the column

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

The characteristic roots of a dynamic system are: 1.7920 1.8160 i, -1.7920 1.8160 i, -0.4160 what is the order of this system? what are the settling time and damping ratio of the system?

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
