Supercell Thunderstorm. A Supercell Thunderstorm is an extreme thunderstorm that produces hail‚ rain‚ and tornadoes. They can last for several hours. They form when warm and humid air starts to spin and rise‚ Once this has happened a wind shear tarts to form a wind shear is basically the wind changes the direction of the horizontal wind. This creates an updraft that is warmed by the sun. The warm buoyant air lifts the vortex into a vertical position and creates a storm. The stronger two of the vortices

Light wooden framed buildings were originally discovered when light partition walls were capable of forming a construction system by themselves. The system consists of timber studs frames assembled on site and tilted vertically or horizontally depending and what is needed. The idea was improved and accelerated with the availability of cheap mass produced nails and properly planed and cut pieces of wood. The first step to building a light timber platform building is to lay foundation walls to support

In this article the influence of the important resistance spot welding process parameters on the shear-tensile strength of the welded joints of Inconel alloy 625 was investigated. Experimental study using full factorial design of the welding current‚ welding time‚ and electrode force parameters was conducted. In order to identify the influence of each parameter and their interaction a general linear model and a second order model using response surface method was developed. Nonlinear correlation

5.0 References | 9 | Executive Summary Many Meteorological phenomena have been identified as being directly hazardous to aircraft in flight. This report focuses on two of these: Microbursts and Aircraft Icing. The first being a localised wind shear event caused by rapid cooling and descent of a column of air‚ the second being the build-up of ice on an aircraft as it flies through certain conditions. Each weather condition is explained in detail‚ with emphasis on how and why it is dangerous

Adding Enzymes to Improve Beef Tenderness By Chris R. Calkins‚ Ph.D. and Gary Sullivan‚ University of Nebraska Importance of Beef Tenderness Beef palatability is affected by many factors and tenderness is cited as one of the most important. Consumers are willing to pay a premium for a guaranteed tender product with the potential to increase the value of the middle meats over $60 per carcass (Miller et al.‚ 2001). Consequently‚ the meat industry is in a continual search for methods to improve the

made of pieces of steel and located out in the sun‚ for a few weeks. In the mean time‚ while Colonel Nicholson was spending his time in the room‚ a few of the prisoners tried to escape‚ but only one of them was successful‚ that person was Commander Shears‚ who will later be one of the members of the group sent to bomb the bridge. After Nicholson got out‚ all the soldiers started to look up to him and he persuaded them to build a proper bridge‚ unlike the shaggy wooden structure‚ that the Japanese were

LIGHTNING Lightning is a massive electrostatic discharge caused by unbalanced electric charges in the atmosphere‚ and resulting in a strike‚ from a cloud to itself‚ a cloud to a cloud or a cloud to ground‚ and accompanied by the loud sound of thunder. A typical cloud to ground lightning strike jumps a 5 km (3 mi) gap through the air.[1] A typical thunderstorm has three or more strikes per minute at its peak.[2] Lightning is usually produced by cumulonimbus clouds based 5–6 km (3-4 mi) above the

Activity 1.1.2 Simple Machines Practice Problems Answer Key Procedure Answer the following questions regarding simple machine systems. Each question requires proper illustration and annotation‚ including labeling of forces‚ distances‚ direction‚ and unknown values. Illustrations should consist of basic simple machine functional sketches rather than realistic pictorials. Be sure to document all solution steps and proper units. All problem calculations should assume ideal conditions and no friction
