In a tensile test, a material fractured before necking. The true stress and strain at fracture were 630 MPa and 0.18 respectively.
(b) what is the length and diemeter at fracture? if the length (lo) and diemeter (Do)
specimen are 30 mm and 6 mm, respectively.

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.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

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
