Wind shear

particular outbreak was caused by a trough that spanned the South of the United States. A cyclone formed around this low pressure band and began to gather momentum. This trough was then met from behind by a jet stream which led to an extremely high wind shear. The temperatures in the affected areas were also fairly high, ranging from 70° to 90°. All of these conditions contributed to an environment that was extremely conducive for tornadic…

This causes lifters to struggle to get the weights off the floor, but makes lockout easy. One thing to be cautious of when conducting a conventional style deadlift is shear force from hyper extending the lower back. (Ez) According to a study of two male regional powerlifting champions, research showed that there were greater L4-L5 shear forces and moments in the conventional group. The research also showed that hip and knee moments were not significantly different between the two deadlift…

1) What are engineering stress and strain? Answer: Engineering Stress: Engineering stress is also called nominal stress, and it is defined as the applied load divided by the original cross sectional area of the material. Engineering Strain: Engineering strain is defined as the amount of material that deforms per unit length in a tensile test. Engineering strain is also known as nominal strain. 2) In the figure below, graphically show the toughness of three class materials:…

discovered of the first ±45° specimen. The Laminate Strength properties are in Table 4 and the In-Plane Shear properties are in Table 5. The plot of Stress vs Strain is in Figure 8 (a) found the Major Young’s Modulus (Ex) region is in Figure 8 (b). The Poisson’s Ratio region is plotted in Figure 8 (d). The Lamina Shear Stress vs Lamina Shear Strain plot (Figure 9, graph a) was used to calculate the Lamina Shear Modulus (Figure 9 (b)). The type of fracture of this specimen was a brittle…

tool tip would be separated. Although the initial method was simple and had advantages, it was not capable of surface roughness prediction and account for fracture. The method predicted different types of chip morphology, such as continuous chip, shear localized chip with and without complete chip…

This phenomenon suggests that the slime is a non-Newtonian substance that their viscosity will be affected by shear stress. In this measurement the shear stress is gravity. As gravity is pulling the slime down, the slime in observation #1 immediately changed its shape just like a fluid. The bonds in that slime does not lock tight that it loosely stretched like glue or liquid. In observation…

Many of things that we interact with are solids and liquids. However, there are some things that are combination of both called a Non-Newtonian Liquid, an example of this is oobleck. This substance has the qualities of a liquid but also has the qualities of a solid when under pressure. One of its qualities as a liquid is its ability to flow, known as viscosity. In this experiment will change the oobleck’s viscosity by changing its thickness. Additionally, applying any pressure to oobleck helps…

back-packer. Efforts to locate him are underway, however the rough seas are preventing boats from searching the area until the storm clears. On land, the streets of Adelaide are littered with tree branches as the wild weather continues, the heavy rain and wind shows no signs of stoping soon. (photo of home, with tree collapsed on top) Southern Suburbs have been affected heavily by the storms. Homes in Noarlunga have faced devastation due to falling trees; part of residents Vincent and…

(Illustration 2)” and hurricanes, it is “The Saffir-Simpson Hurricane Wind Scale.(Illustration 1)” Below are two tables that show the differences between the two scales and the different categories. They show the damage they cause and the wind speeds that they have when they hit a certain point on the scales. The two scales are almost very similar to each other and they both seem to cause the same type of damage the higher up they go, the wind speeds are a little different but they look to cause…

OUTLINE Hurricanes are enormous storms which have winds exerting great force upward and inward at very great speeds like 100 to 200mph. Every hurricane can last for over a week. A hurricane is a bit different from the usual cyclone. Cyclone winds have a very low speed of 9km. Hurricanes, cyclones and typhoons are all the same but with a different name. Meteorologists predict the changes in the weather and use different tools to measure changing condition in the atmosphere. The most common…
