Introduction of Lab 5: Analysis of a Zinc: Aluminum Alloy The analysis of a metal alloy was designed to learn how to use the Ideal Gas Law (formulas listed below) in a laboratory setting in relevance to acquiring moles of gas created‚ thus giving us one step closer to finding the molar mass. The importance of the Ideal Gas Law‚ as well as the other gas laws‚ is that it signifies the relationship between the properties of an ideal gas. These properties assist in the explanation of the Kinetic Molecular

fuselage. The spar carries flight loads and the weight of the wings while on the ground. Hence‚ in order to do the materials for a wing spar needs to be very strong and highly elastic. For the Boeing 737‚ the spars of the wings are made up of aluminium alloy 7178 which mainly consists of aluminium‚ zinc‚ magnesium‚ chromium & copper composites. In this section‚ we will briefly descript the aluminium 7178 properties‚ its test standard‚ reasons why this material are chosen to make this part of the wing spar

Where It All Started Today Baseball is considered America ’s national pastime. American ’s began playing baseball on informal teams in the early 1800 ’s. At this time they had only local rules that differed from place to place. Also‚ at this time there were no official baseball bats for the players to use. Many used sticks as bats. That is where stick ball came from which is still played today. Baseball was based on the English game of rounders. Alexander Joy Cartwright of New York invented

Resistance of Commercial Aluminium Mayeedul Islam 1‚*‚ S. M. Najmul Hoque2‚ M. Abdullah Al Mahmood2‚ A. A. Shisir 2 ABSTRACT Aluminium and their alloys are widely used as construction materials from house hold appliances to air-craft parts. The commercially pure aluminium has merely low corrosion resistance and hardness compare to aluminium alloy. In this study an attempt has been made to study the influence of heat treatment on the properties of commercially pure aluminium. The investigation

Scandium is the 21st element on the periodic table. This element can be located in the 4th period 3rd . The symbol for Scandium is Sc on the periodic table. Scandium is used for and is in many things. For example it is used to help grow crops such as corn‚ peas‚ and other seed grown plants. There are many protons and neutrons in Scandium. There are 21 protons‚ 24 neutrons‚ and 21 electrons. Scandium is also used in tracking devices. Scandium was discovered in Sweden 1879‚ by Lars Fredrick Nilson

Metals and alloys for nuclear energy There are two important ways in the making of nuclear energy: nuclear fission and nuclear fusion. Fusion and fission have a different working mechanisms‚ thus other materials are used. In a nuclear reactor fuel rods are bombarded with neutrons causing fission of the fuel. This way energy is released. With this energy water is heated to steam and with the use of heat exchangers and steam turbines electricity is generated. As fuel is usually uranium used‚ but also

MKTG 410 Week 6 Case Study AOL Goes Far East 1. Was Mitsui the best partner for AOL to enter the Japanese market? If so‚ why? If not‚ who (or what kind of company) would make a better partner? Why? Mitsiu being an established company in Japan‚ had the expertise and history to become a joint venture‚ but not with AOL. Even though the company is well established as an MNC in 60 countries and respected by Japanese corporations and consumers for their goods and services. (Kotabe)
