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.

weight before breaking. The four main types of bridges are: beam‚ arch‚ suspension and cantilever. The most commonly used bridge is the beam bridge. The beam bridge is made up of a horizontal structure and two or more vertical structures on either end for the horizontal structure to rest on. Beam bridges can be as simple as a fallen log across a river. In society‚ engineers generally make beam bridges out of steel and concrete. Because beam bridges‚ or any bridge for that matter‚ are required to

Abstract --- Reutilization of waste materials in the building industry helps to prevent environmental pollution whilst contributing to the design of more economical buildings. Over the years‚ there has been increase in the accumulation of tyre rubber due to the increase in the production of vehicles. Sometimes this waste tyre rubber is burned which leads to environmental pollution. So the use of this type waste tyre rubber for the replacement of aggregates in concrete leads to the decrease in the

the objective is to establish a relationship between the length of a cantilever‚ which may give some insight into the physics of cantilevers. Hypothesis: If one increases the length of a cantilever‚ one would expect there to be an increase in deflection/flexion of the cantilever. Similarly‚ if one increases the mass of the load‚ one would expect there to be an increase in the deflexion/flexion of the cantilever. In addition‚ I predict that proportionality will also occur between the independent

TENT STRUCTURES Definition of a Tent Structure: A membrane structure pre-stressed by externally applied forces so that it is held completely taut under all anticipated load conditions. To avoid extremely high tensile forces‚ a membrane structure should have relatively sharp curvatures in opposite direction (Reference: The Visual Dictionary of Architecture‚ Ching). Purpose: The purpose of a tent structure is to provide a means of shelter that is lightweight‚ portable‚
