2.1.8.4. Tensile strength: Lightweight and normal weight concretes have similar tensile strengths, though lightweight exhibits greater variability. The tensile strength of normal weight concrete of equal compressive strength may vary within a wide range depending, among other parameters, on the shape and surface texture of the aggregate. Experimental tests indicate that the tensile strength of concrete is highly variable and ranges from a bout 8-12% of its compressive strength. The actual value depends
The tensile test, as known as the “tension test”, is one of a most fundamental type of mechanical test that used on a material. Tensile test is really inexpensive which makes this test more preferable. From tensile test, how the material will react to forces being applied in tension can be determined. As the material is pulled by machine, material’s strength can be found along its elongation. From the stress-strain curve of the tensile test, the values which can be found are Modulus of Elasticity
Title: Testing the strength of plant fibers Objectives: To develop knowledge and understanding of the strength of plant fiber in a plant stem. To develop problem solving and experimental skills, for example, information is accurately processed, using calculations where appropriate, experimental procedures are planned, designed and evaluated properly, the use of microscopes, producing valid results and recording results. To develop techniques of measuring the size of plant fibers under microscope

and biodegradable garbage bags that easily decompose when disposed. CHAPTER II MATERIALS AND METHODS A. Materials Plastics are composed of three basic parts: polymers, plasticizers and additives. Polymers give plastic its strength, plasticizers give it its bendable and mouldable qualities, and additives give it other properties (color, durability). For the research’s materials, the potato starch and agar-agar serve as the biopolymers while the glycerol serves as the plasticizer
2.3 Diverter Applications The diverter is located at the bottom of the torus shaped vessel and is designed to extract heat from the plasma as well as the ‘exhaust fumes’ of the reaction occurring which are helium and any impurities from the first wall of the reactor. The basic concept of a diverter used within a tokamak design can be understood better by looking at figure x which is a diagram of JET after it had a divertor fitted. The separatrix is the last field line which contains the plasma. The

INTRODUCTION 1.1 PRODUCT IDENTIFICATION Home cinema is a set of entertainment systems that are used in the home to imitate the experience and feeling that is gotten from the movie theatre. They try as much as possible to give you the so much yearned for theatre experience. 1.2 DESCRIPTION OF THE HOME CINEMA AND ITS PARTS The home cinema is made up of different set of components that enable the theatre experience. A typical home cinema will include some or all of the following: 1. Input devices
methods such as artificial neural networks(ANN) using software (pythia) and response surface methodology (RSM) to predict the tensile strength, the percentage of elongation and hardness of friction stir welded 6061 aluminum alloy. An artificial neural network (ANN) model was developed for the analysis of the friction stir welding parameters of Al 6061aluminum pipe. The tensile strength, the percentage of elongation and hardness of weld joints were predicted by taking the parameters Tool rotation speed,
manufacturing of power transmission chains, because its price is relatively low and it provides acceptable material properties for many applications. Its low carbon content (0.05-0.15%) makes it malleable and ductile. Although it is relatively lower in tensile strength, its
