Another unknown was tested using this procedure. Upon the addition of 6M NH3 and 6M HNO3, no precipitate formed. (NH4)2CO3 was then added. A precipitate formed and the mixture was centrifuged and decanted. The liquid was then transferred to a small beaker and heated to dryness. Once cool, 1M H3PO4 and 1M Na2HPO4 were added to re-dissolve the solid, and the solution was divided into two test tubes. To the first, solid KI was added; no change was observed. To...

A polymer rod is tested to determine its viscoelastic response. The rod’s cross-section is square with the side of 5mm. The rod’s length before loading is 500mm. A tensile force of 500N is applied to the rod and the rod’s length under load was measured as a function of time. Instantly after applying the load, the rod is stretched to 508mm. After 24 and 48 hour under load, the rod’s length was measured as 550mm and 570mm, respectively. The load...

Find a materials property plot of elastic modulus and density. Identify a composite, a polymer, and a metal with densities less than 3000 kg/m3 (Mg = 106 g) and the highest possible elastic modulus. Provide an example of an engineering design that might require this combination of material properties and explain why those properties would be important. What design advantages could a polymer offer over a metal even though the polymer has a lower stiffness?
