Question B6. Which of the following is not correct? (a) The modulus of timber depends on the density of the timber. (b) Timber is a composite based on cellulose polymers which means that its properties are time dependent and timber will creep with time under load. (c) The toughness of timber is reduced by the presence of knots and defects in the structure. (d) Timber is usually dried before use to reduce its moisture content and reduce warping during use....

Question: Create Young’s modulus-melting point (E-Tm)
chart (level 2) for metals and alloys. Use ‘guideline’ function to
determine which slope among 0.5, 1 and 2 in the E-Tm
chart best describes the dependence between E and Tm.
Justify this dependence from the origin of these two
properties.
I had already drawn the picture. Could you explain the
reason why Yong's modulus and melting point have a linear
relationship? Justify this dependence from the origin of these two
properties.!!!!

Assignment Details Aluminium alloys are very widely used in the industry as structural metals, second only to steel. Pure aluminium is very soft, light in weight and low melting point which makes it quite popular for various applications. However, adding alloying elements to aluminium enhances various physical properties making it even stronger and versatile for numerous engineering applications. Answer the following questions 1. Identify the following information for pure aluminium: Atomic number Atomic mass Atomic radius Crystal structure Density Periodic...

A material may fail in many ways; in a ductile or brittle mode; by creep or fatigue; by corrosion or stress corrosion; by hydrogen or liquid metal embrittlement; by slow tensile overload or by impact. An examination of the failure may tell you a lot about the material and the failure mode. In this course, you have learned (we trust) the correlations between structure-properties,...
