Astress-strain test is performed on an aligned fibrous composite such that the force is applied in the longitudinal direction. during the initial stage of the test, which phase bears most of the load? draw a picture of this loading.

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

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

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
