Assuming that the deformation is entirely elastic‚ calculate the modulus of elasticity of the aluminum. 6.24 Figure 6.21 shows the tensile engineering stress-strain behavior for a steel alloy. a. What is the modulus of elasticity? b. What is the proportional limit? Approximately 1370 MPa (200‚000 psi). c. What is the yield strength at a strain off-set of 0.002? 1570 MPa (228‚000 psi). d. What is the tensile strength? Approximately 1970

Laura Speirs June 13‚ 2011 Professor Nalley Tungsten Paper Tungsten Tungsten is a gray-white metallic element that is stable and is very resistant to acids and bases. It does‚ however‚ oxidize in air‚ especially at higher temperatures Tungsten was discovered by Juan José and Fausto Elhuyar‚ Spanish chemists and brothers‚ in 1783 in samples of the mineral wolframite ((Fe‚ Mn)WO4). Tungsten was named from the Swedish words "tung sten" meaning "heavy stone." Tungsten ’s chemical symbol comes from

Nautilus v. Biosig: The Reasonably Certain Standard Introduction In Nautilus v. Biosig Instruments‚ the U.S. Supreme Court rejected the Federal Court’s “insolubly ambiguous” standard for finding indefiniteness under 35 U.S.C.A 112. Under that standard‚ a claim is indefinite if it is “insolubly ambiguous” and “not amendable to construction”. The Court in its place articulated a new standard under which a “patent is invalid for indefiniteness if its claims‚ read in light of the specification delineating

vs. Young’s modulus. In this plot‚ only material with K1c >15MPam0.5 are considered. The same plot is used to solve part b) and c). For part a)‚ material of highest K1c is to be chosen. According to the plot‚ the best material for wire ropes is low alloy steel. 2. Energy-limited design – spring in pegs The torsion springs in clothes pegs store energy that is pre-applied to them. The energy they are able to store determines how much force they can apply to the wooden part of the pegs and hence

Alloy - An alloy is a substance made by melting two or more elements together‚ at least one of them a metal. An Example: Examples of alloys include brass‚ bronze‚ 14k gold‚ and sterling silver. covalent bond - A covalent bond is a chemical link between two atoms in which electrons are shared between them. An Example: There is covalent between the oxygen and each hydrogen in (H 2 O). Each of the bonds contains two electrons - one from a hydrogen atom and one from the oxygen atom. Both atoms
