Technical Report The Construction of Alloy Wheels

Technical Report The Construction of Alloy Wheels Dan Peart A223245 Integrating Studies Introduction Aluminium alloy wheels are now used in all branches of Motor Racing, ranging from Touring cars and Rally cars to Formula One cars. The Alloy wheels offer far superior mechanical properties than the conventional steel wheels formerly used. These benefits include reduced un-sprung weight, i.e. not held by the suspension, providing more precise steering input and improved responsiveness. Alloy wheels also improve acceleration and braking due to the reduction of weight. The added strength of a quality alloy wheel can significantly reduce wheel/tire deflection in cornering. This is particularly critical with a vehicle equipped with high performance tires where lateral forces may approach 1.0g. The metals in alloy wheels are excellent conductors of heat - improving heat dissipation from the brakes - reducing risk of brake fade under demanding conditions. Additionally, alloy wheels can be designed to allow more air to flow over the brakes, this can help cooling. The alloy used in the finest road wheels today is a blend of aluminium and other elements. The term "mag wheel" is sometimes incorrectly used to describe alloy wheels. Magnesium is generally considered to be an unsuitable alloy for road usage due to its brittle nature and susceptibility to corrosion. Nowadays, there

To find out whether the foods contain starch, fats, proteins and glucose or not.

Title: Food test Aim: To find out whether the foods contain starch, fats, proteins and glucose or not. Introduction: We have to eat food everyday. Why do we have to eat so much types of food, to keep healthy? Because the foods contain a lot of nutrients, nutrients are substances which organisms need for releasing energy, for growth and repair, and to sustain and all life processes. And they are good for our health. For example: proteins can help us to grow. So we want to find out what types of nutrients are in the food that we eat; starch, fats, proteins or glucose? So we use the method down here to find out: Iodine test: it's the method that we use to find out if the food contain starch or not. We can see the change when we add iodine solution to the substance. If the color of the iodine solution changes from brown to dark blue or black, then that means the food contains starch. If the color of the iodine solution did not change, then that means that the food does not contain starch. Benedict's test: it is the method we use to find out if the foods contain sugar or not. If the food contains sugar, then the color of the solution will change from blue to orange. They changed from blue to green, green to yellow and then yellow to orange. If there is a lot of sugar in the substance, then maybe the color will change from orange to red, too. Biuret test: it's the method

Although cow's milk is the most popular in many countries, milk can be obtained from many different sources.

Although cow's milk is the most popular in many countries, milk can be obtained from many different sources. For example, milk from goats and sheep makes a substantial contribution to the total milk production in countries of Eastern and Southern Europe, Malawi, and Barbados, whereas the water buffalo is a common source of milk in much of Asia. The table below illustrates some of the differences in composition between these milks. Woman milking a goat Milk is a perishable commodity and spoils very easily. Its low acidity and high nutrient content make it the perfect breeding ground for bacteria, including those which cause food poisoning (pathogens). Bacteria from the animal, utensils, hands, and insects may contaminate the milk, and their destruction is the main reason for processing. This preservation of the milk can be achieved by fermentation, heating, cooling, removal of water, and by concentration or separation of components, to produce foods such as butter or cheese. The degree to which milk consumption and processing occurs will differ from region to region. It is dependent upon a whole host of factors, including geographic and climatic conditions, availability and cost of milk, food taboos, and religious restrictions. Where processing does exist, many traditional techniques can be found for producing indigenous milk products. These are more stable than raw

How important is a balanced diet in maintaining good health?

How important is a balanced diet in maintaining good health? A healthy and well balanced diet is the body's main energy source. In adults, it encourages regeneration and self-healing within the body. In children, it constitutes the building blocks for future health as well as producing energy. A well balanced diet will provide the body with all the essential nutrients it needs. This will be achieved by eating a variety of foods from each food group. A pyramid of food groups is shown in appendix A. There are many different nutrients in each food group; about 50 are known to be essential to human life. Carbohydrates, proteins, minerals, fats and vitamins are the five types of food nutrients. Water can also be classed as a nutrient as it is essential to life. The following assignment aims to describe the functions of the major food nutrients above. The recommended daily allowance (RDA) of nutrients needed for healthy living depends on age, sex, and degree of activity. Larger amounts of certain nutrients are needed throughout life. These are called macronutrients. Fats are one of the three macronutrients and can be divided into two categories, saturated and unsaturated. Fats are an important part of the diet as they provide a source of energy. It is stored under the skin where it acts as an insulator and also stores certain vitamins. The building blocks of fat are fatty acids

Give a detailed account of the Jewish food laws and their origin.

4a) Give a detailed account o the Jewish food laws and their origin. "These are the animals which you may eat...anything which has a completely split hoof and chews the cud, this you may eat." Food that is allowed to be eaten is known as "kosher" meaning "fit" or "correct" in accordance with the Jewish law. The opposite of Kosher is Treifah. Kashrut is complicated in the modern world because there are so many processed foods with additives which may be Treifah. Some Jewish food producers ask a Rabbi to supervise production. They certify that the food is Kosher so that the Jews will feel able to eat it. Rabbis also analyse other products and issue lists of brand names which are Kosher. Orthodox Jews refer to these lists when shopping. Vegetables and cereal products easily pass the test as long as they are washed clean of insects or bugs. All plants are kosher but not all animals. Other foods have to fulfil far more requirements, especially meat. First only certain animals are permitted to be eaten. These animals are ones which both chew the cud and have split hooves. Cud is the name given to the little balls of grass that certain animal forms in their stomach after swallowing it. This includes cattle, sheep, goat and deer. They have to fulfil both of these requirements so that pigs are rejected, as they do not chew the cud. Birds of prey are not acceptable but poultry are.

How Microwave Ovens Work

How Microwave Ovens Work by Omar Davison The microwave oven is one of the great inventions of the 20th century - millions of homes in America have one. Microwave ovens are popular because they cook food incredibly quickly. They are also extremely efficient in their use of electricity because a microwave oven heats only the food - nothing else. A microwave oven uses microwaves to heat food. Microwaves are radio waves. In the case of microwave ovens, the commonly used radio wave frequency is roughly 2,500 megahertz (2.5 gigahertz). Radio waves in this frequency range have an interesting property: water, fats and sugars absorb them. When they are absorbed they are converted directly into atomic motion - heat. Microwaves in this frequency range have another interesting property: most plastics, glass or ceramics does not absorb them. Metal reflects microwaves, which is why metal pans do not work well in a microwave oven. How Microwave Ovens Cook Food You often hear that microwave ovens cook food "From the inside out." What does that mean? Here's an explanation to help make sense of microwave cooking. Let's say you want to bake a cake in a conventional oven. Normally you would bake a cake at 350 degrees F or so, but let's say you accidentally set the oven at 600 degrees instead of 350. What is going to happen is that the outside of the cake will burn before the inside even
