- A cylindrical rod 100 mm long and having a diameter of 10.0 mm is to be deformed using a tensile load of 27,500 N. It must not experience either plastic deformation or a diameter reduction of more than 0.00075 mm. Of the materials listed as follows, which are possible candidates? Aluminum E=70GPA, Yield Strength 200 MPa, Poisson's ration 0.33 Brass E=101GPA, Yield Strength 300 MPa, Poisson's ration 0.34 Steel E=207GPA, Yield Strength 400 MPa, Poisson's ration 0.30 Titanium E=107GPA, Yield Strength 650 MPa, Poisson's ration 0.34All factors that influencing on tensile strength properties also influence on impact strength except crystallinity and molecular weight factors * True False Carbon black is one of the additives can be dissipate charges on the surfaces of polymeric materials: * True O False Stress-strain curve is also suitable for determining the impact strength via difference in corresponding strain * True FalseQ11

Vials. 2 - mL colored alcohol, 2 - mL kerosene Materials : Theory: Density is best described as the compactness of a substance. The more compact is the substance the in a small space the heavier is the substance. For a less dense substance, the mass is spread out over a large volume of space. It is a measurement of how heavy of light is the substance Its mathematical expression is density is the ratio of an object's mass to its volume. The density of a material…
