using Solid Edge to determine the Second Moment of Area for the different cross-sections. [pic] Equations Use units: Force (N)‚ Length (mm)‚ Stress (MPa) E = Young’s Modulus or Mod of Elasticity (MPa) I = 2nd Moment of Area or Area Moment (mm4). Can calculate using SolidEdge sketch. BENDING [pic] In our case‚ we must first convert the mass to Newtons (N). W = kg * 9.81 L is the span length in (mm). I is the Second Moment of Area in (mm4). We can calculate this for a rectangle using

The local area network (LAN) is home to sheer bandwidth and countless client server applications. Different companies have radically different networks; some have a single PC and others have hundreds of locations and thousands of computers. This page is intended to explain the basic principles and components frequently found on the LAN. The internal network is usually built with the highest bandwidth available. It is then connected to a tiny internet connection which is almost always a bottle neck

Surface Area to Volume Ratio and the Relation to the Rate of Diffusion Aim and Background This is an experiment to examine how the Surface Area / Volume Ratio affects the rate of diffusion and how this relates to the size and shape of living organisms. The surface area to volume ratio in living organisms is very important. Nutrients and oxygen need to diffuse through the cell membrane and into the cells. Most cells are no longer than 1mm in diameter because small cells enable nutrients and oxygen

Introduction Urbanization is exponentially growing in the world while rural living is decreasing; over half the world’s population lives in a urban areas (MeyerLindenberg‚ 2015). Urban being defined as an constantly builtup area with 50‚000 or more residents with at least 1‚000 residents per square miles as defined by the United States Census. Urbanized living is accompanied by many risk factors that are common to the development of mental health issues and disorders (Carol Strike‚ Paula Goering

1.0 Introduction In ecology‚ a species-area curve is a relationship between the area of a habitat‚ or of part of a habitat‚ and the number of species found within that area. Larger areas tend to contain larger numbers of species‚ and empirically‚ the relative numbers seem to follow systematic mathematical relationships. The species-area relationship is usually constructed for a single type of organism‚ such as all vascular plants or all species of a specific trophic level within a particular
