MEM23061A Test Mechanical Engineering Materials Lab. BEAM BENDING The bending of beams is one of the most important types of stress in engineering. Bending is more likely to be a critical stress than other types of stress - like tension‚ compression etc. In this laboratory‚ we will be determining the Modulus of Elasticity E (also called Young’s Modulus) of the various materials and using Solid Edge to determine the Second Moment of Area for the different cross-sections.

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

PAPER AND THIN-LAYER CHROMATOGRAPHY Lab 47 Michael Stravino‚ CHM 2211L‚ June 3‚ 2012 Abstract Thin-Layer Chromatography and Paper Chromatography can be used to identify identical compounds‚ unknown compounds‚ the number of components in a mixture‚ as well as other important uses not explored in this laboratory. This experiment explores these techniques to identify an unknown amino acid by TLC and analyze food colors using paper chromatography. By using 2.0 mL of dimethoxyethane and 18 mL of

blue‚ green‚ red‚ and yellow mixtures inside the test tube. Before we even put in the orange solution‚ the yellow liquid started to mix in with the red solution. It meant that the yellow sugar water was more dense than the red sugar water. On our second trial‚ we tried to put the green mixture first to see what would happen. When we put the green mixture inside the test tube‚ we decided to experiment and put in the yellow solution. The second we put the yellow mixture in‚ it immediately mixed in with

Solvent/Water Trap Diagram Rodney Atwaters Halle Bair May 28‚ 2013 Chemistry 36100 Introduction The purpose of this lab was to produce benzoic acid by mixing sodium benzoate with hydrochloric acid. The Hydrochloric acid used in the experiment was a stock solution made by mixing HCl Acid and deionized water. HCl acid‚ historically called‚ muriatic acid or spirits of salt‚ hydrochloric acid is produced from sulfuric acid and common salt‚ NaCl (Princeton.edu). Since the early 1900 ’s‚ sodium

one of the key solutions to the underlying cause of the financial turmoil in history. First of all‚ in 1930s‚ the Great Depression in America triggered considerable debates on the primary cause of the stock market crash. Analysts in favour of separation of banks have observed that the fundamental reason was the “overproduction of securities” resulted from the combination of commercial and investment banks (Casserley‚ Härle‚ and Macdonald‚ 2011). Until 1902s‚ national banks had no authority to issue
