971584 Introduction to Formula SAE® Suspension and Frame Design Edmund F. Gaffney III and Anthony R. Salinas University of Missouri - Rolla ABSTRACT This paper is an introduction to Formula SAE® (FSAE) suspension and frame design based on the experience of the design team at UM-Rolla. The basic theories and methodologies for designing these systems are presented so that new teams will have a baseline for their first FSAE design. Examples will be given based on UM-Rolla’s 1996 FSAE entry.

Empirical Formula of a Compound INTRODUCTION Chemical formulas indicate the composition of compounds. A formula that gives only the simplest ratio of the relative number of atoms in a compound is the empirical formula or simplest formula. The ratio usually consists of small whole numbers. We call a formula that gives the actual numbers of each type of atom in a compound the molecular formula. The numbers in a molecular formula will be whole number multiples of the numbers in an empirical formula. To determine

Introduction The Formula One World Championship was started in 1951 by private sportspersons. Today‚ Formula One is the world’s biggest motor sports event and is arguably the second most popular sport in the world. It consists of ten teams‚ with two cars each‚ contesting a 17-race series. It involves two titles‚ the Driver’s Championship and the Constructors Championship. Formula One today is a highly dependent on technology (Denison and Henderson‚ 2004). This article will discuss the resources

CHEMICAL BONDS Chemical Bonds I. Introduction Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms called a chemical bond. The two extreme cases of chemical bonds are the covalent bonds and ionic bonds. Covalent bonds are bonds in which one or more pairs of electrons are shared by two atoms. Covalent bonds

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test

Today this program‚ renamed Formula SAE ®‚ has become the world championship for college engineering students‚ and the training program for race car engineers and designers around the world. Teams from as far away as Korea‚ Japan and Mexico travel to the suburbs of Detroit each May for the big event. Satellite events have begun in the United Kingdom and Australia. Each year as many as 4‚000 students are members of Formula SAE teams at universities around the world. Nearly 2
