An engineer designing a vibration isolation system for an instrument console models the consoleand isolation system as a 1 degree-of-freedom spring-mass-damper system. The modeled mass is 2kg, the spring constant is 8 N/m, and the damping constant is 1 Ns/m. The system is exposed to atime-varying force acting on the mass. This force measured is approximated by:F(t) = 20 sin(4t) [N]. Determine the steady-state response of the system to this input.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
