(a) Compute the Poisson’s ratio for a material that is undergoing a uniaxial tensile test with zero dilation. (b) A student was given three different unidentified materials to determine their Posson’s ratio. She determined the Poisson’s ratios to be 0.5, 0.3, and 0. She needs your help in identifying the class of material for each of these values.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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
