DRAWING AND ITS PROCESSES Drawing is a metalworking process which uses tensile forces to stretch metal. It is broken up into two types: sheet metal drawing and wire‚ bar‚ and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire‚ bar‚ and tube drawing the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually done at room temperature‚ thus classified a cold working process

I.Case Analysis Overview Cumberland Metal Industries (CMI) is one of the largest metal manufacturers in the world. The company evolved from selling metal as a finished product to one that used it as a raw material‚ increasing sales from $250‚000 in 1963 to over $18‚500‚000 in 1979. Currently‚ CMI relies heavily on SlipSeal‚ which is used as a high-temperature sealant in automobiles. Although CMI dominates the market for this product‚ corporate sales figures decreased over the last year. As a

The purpose of this lab was to model the significant differences in density that oceans experience when glaciers and polar ice caps melt. It demonstrated that the variation in density greatly affects salt water. I discovered that the increase in freshwater causes a decrease in density. I made three claims. First‚ the higher the salinity of the water is‚ the denser it will be. This was shown in my data by the fact that‚ with 0mL of fresh water‚ the density was 1.108 g/mL For every milliliter of fresh

Background: Cumberland Metal Industries (CMI) was one of the largest manufacturers of curled metal products in the country.Their sales grew from $250‚000 in 1963 to over 18‚500‚000 by 1979.It originally custom fabricated components for chemical process filtration and other highly technical applications. The company’s philosophy soon evolved from selling the metal as a finished product to selling products that used it as a raw material . Earlier CMI used to sell exaust gas recirculation(EGR) valves

SOLUTION AND CONCENTRATION A solution is a homogeneous mixture‚ made up of a solute dissolved in a solvent. Ex. In a water (aqueous) solution of sodium chloride‚ the sodium chloride is the solute and the water is the solvent. Solute – the component that is dissolved or is the least abundant component in the solution. Ex. Sugar‚ salt Solvent – the dissolving agent or the most abundant component in the solution. Ex. Water Common Types of Solution State of Solution State of Solute

composed of just one of these substances". Bile is a greenish-brown liquid produced in the liver then stored in the gallbladder which is use to digest fat. Bile contains water‚ cholesterol‚ fat‚ bile salts‚ proteins and a waste product call bilirubin. If the bile has too much cholesterol ‚ bile salt‚ or bilirubin‚ they hardens into stones. There are two types of Gallstones. The first and more common type is known as the Cholesterol Stone‚ which accounts for 80 percent of all cases of Gallstones

Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants

Saline Salt Company Analysis The Saline Salt Company production process was simple. Their process involved extracting salt from six tanks of 900‚000 cubic feet of seawater which could only be held on a large plot of land. As land becomes more valuable and rarer‚ expansion of the existing method becomes very difficult. Saline Salt Company could not compete with other companies that were producing larger amounts of salt in shorter amounts of time. Saline Salt Company did not expand as the needs
