An aluminum bar is attached to rigid (immovable) walls on both ends as shown below. The temperature where the bar experiences no stress is 20OC. Calculate the temperature when the bar reaches a compressive stress of 100 MPa and the temperature when the bar reaches a tensile stress of 15 MPa. EA = 70x103 MPa, and αA = 2.3x10-6 m/m/OC. Aluminum = 2m

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

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?
