The graph of the viscosities at the tested temperatures for the 65 wt% sucrose solution can be seen in Figure 2. In both graphs error bars are included, but due to scale an the small amount of error, they cannot be seen. The viscosities collected by the class at each temperature versus concentration are graphed in Figure 3. The complete set of data from the class can be found in Appendix B.
Introduction: The objective for the lab was to determine properties of materials by using a tension test. The properties that were determined was Young’s Modulus, ultimate tensile strength, and yield strength. Three aluminum alloys were tested. The first was the AA 2024 , which is high strength used in aerospace applications. The second specimen was AA 5052, which had low strength, but high ductility.
hydrogen bomb or H-bomb, weapon inferring an extensive bit of its vitality from the atomic combination of hydrogen isotopes. In a nuclear bomb, uranium or plutonium is part into lighter components that together weigh not exactly the first iotas, the rest of the mass showing up as vitality. Not at all like this splitting bomb, the hydrogen bomb capacities by the combination, or joining together, of lighter components into heavier components. The deciding item again weighs not as much as its parts, the distinction afresh showing up as vitality. Since to a great degree high temperatures are required with a specific end goal to start combination responses, the hydrogen bomb is otherwise called an atomic bomb.
The two properties that make the metal tungsten a good material for the filament of a light bulb is it has the highest melting point and it 's the greatest tensile strength out of all metals. Since tungsten has those amazing properties it is used for light bulb filaments. This metal melting point is 6,191 degrees Fahrenheit. It is a dull silver metal known as one of the toughest things found in nature. Tungsten can be combustible.
It can also reacts with oxygen at high temperatures. Gadolinium has a hexagonal closely packed structure at ambient temperatures, but transforms at temperature of 1262 degree Celsius to a body centred cubic structure. This metal is paramagnetic at room temperature, but becomes ferromagnetic (strongly attracted by a magnet) when cooled below 20degrees Celsius and also shows the magnetoric effects ( meaning that when entering magnetic fields its temperature rises and its temperature decrease when exiting magnetic fields. Gadolinium has a greatest ability to capture thermal neutrons of all elements; and stable in dry air, but tarnishes off in moist environments forming gadolinium (III) oxide. It has a melting point of 1585K (which is the same as 1312°C 2394°F), heat of fusion of 10,05 kJ/mol, and boiling point of 3546 K( 3273 °C, 5923 °F).
Ductile/brittle Fracture Ductile materials are materials which displays large numbers of plastic deformation, while brittle materials show little or no plastic deformation before fracture. The diagram is the a tensile stress-strain curve, which represents the degree of plastic deformation exhibited by both brittle and ductile materials before fracture. Crack initiation and propagation are vital to fracture. The manner in which the crack propagates through the material gives great insight into the mode of fracture. In ductile material ( ductile fracture), the crack moves slowly and is assisted by large amount of plastic deformation.
It was the most powerful quake ever recorded. Earthquakes will occur on most plate boundaries, other than constructive as this is where new land is formed by magma moving into the gap on the plate boundaries (Alvarez, et al., 2014). Mostly happen on subductive and conservative plate boundaries examples of which are East Asia, when these boundaries crush against each other and create pressure. Eventually, the pressure will build up to a point where it overcomes the friction holding two sections of rock together. The sections will slip, relieving the pressure and creating an earthquake as the energy that was held in the two sections is transferred into seismic waves, also known as an earthquake (Alvarez, et al., 2014).
The tensile strength of the material increases because the subsequent application of tensile stress must nullify the compressive prestress. • This can result in improved structural capacity and serviceability compared to conventionally reinforced concrete. • High-strength tendons are used to produce compression. They are made of high- tensile steels, carbon fibers etc. and consist of threaded bars, single or multiple
In addition, a weak disorder-induced feature at 1620 cm-1 can also be observed in Raman spectra of shock-synthesized samples. Based on these results, we can conclude that shock loading can not produce pristine graphene, but graphene with many defects due to its extreme loading process. Shock wave action generates high temperature, high pressure and high strain rate. This extremely nonequilibrium 12 process may induce considerable defects in shock-synthesized products. This has also been verified in shock synthesized diamond and graphite .
Matthew Brayton Physics Measuring Lab Report: Purpose: To practice measuring, calculating uncertainty, and creating data tables. In this lab we measured 5 things - The surface area of the top of the one table, the volume of the room in square meters, the width of a single piece of paper, the length of my foot, and the circumference of my head. Data Table for the surface area of the top of one table: Length l /cm +/- 0.4cm Average Length (LAvg) / cm +- 0.4 cm Width (w) /cm +/- .3 cm Average Width (WAvg) /cm +/- .3cm Average Area (AAvg) /cm^2+/- 0.7 cm^2 Average Area (AAvg) / m^2 +- 0.006 Uncertainty of Average Area (UncAA) / m^2 122.1 122.2 60.4 60.4 7375 0.7375 0.006 122.3 60.2 122.1 60.5 Note: We measured our table in the classroom
