and for developing new Materials that better suit a specified use. This lab tested two materials mild steel and cast iron. The data from each test was used to determine valuable material properties such as ultimate tensile strength‚ modulus of elasticity‚ and yield strength. Other calculated properties included true fracture strength‚ percent reduction of area‚ and percent elongation. These material properties were used to define the material as brittle or ductile.

1.0 Abstract The elastic modulus‚ yield point‚ and ultimate strength of mild steel were determined in uniaxial tension. The "dogbone" specimen geometry was used with the region of minimum cross section having the dimensions: thickness =1.04 mm‚ width = 3.14 mm‚ and length section = 30 mm. This experiment was accomplished by first placing our specimens one at a time into a tensile testing machine (A G.U.N.T Hamburg Tensile Testing Machine (Max. load = 2kN))‚ which‚ under physical control‚ slowly

Engineering materials Choice of materials for a machine element depends very much on its properties‚ cost‚ availability and such other factors. It is therefore important to have some idea of the common engineering materials and their properties before learning the details of design procedure. Common engineering materials are normally classified as metals and nonmetals. Metals may conveniently be divided into ferrous and non-ferrous metals. Important ferrous metals for the present purpose

INFORMATION COURSE TITLE: ENGINEERING LABORATORY III (BDA 27101) TOPIC 1: TENSILE TEST 1. INTRODUCTION The tensile experiment is the most common mechanical test that reveals several important mechanical properties‚ such as: modulus of elasticity‚ yield strength‚ ultimate tensile strength‚ ductility‚ and toughness. The material to be tested is formed into a shape suitable for gripping in the testing machine‚ and then pulled at constant rate until it fractures. The tensile instrument elongates

CHAPTER 27. FLEXIBLE PAVEMENT DESIGN NPTEL May 24‚ 2006 Chapter 27 Flexible pavement design 27.1 Overview Flexible pavements are so named because the total pavement structure deflects‚ or flexes‚ under loading. A flexible pavement structure is typically composed of several layers of materials. Each layer receives loads from the above layer‚ spreads them out‚ and passes on these loads to the next layer below. Thus the stresses will be reduced‚ which are maximum at the top layer and

Simple Stresses Simple stresses are expressed as the ratio of the applied force divided by the resisting area or σ = Force / Area. It is the expression of force per unit area to structural members that are subjected to external forces and/or induced forces. Stress is the lead to accurately describe and predict the elastic deformation of a body. Simple stress can be classified as normal stress‚ shear stress‚ and bearing stress. Normal stress develops when a force is applied perpendicular to the cross-sectional

This is known as shifting the burden of the tax and the ability of businesses to do this depends on the price elasticity of demand and supply. The diagram below shows the
