    1216 Words  | 5 Pages

    CHAPTER ONE: Introduction 1.1 General: Plane and/or reinforced concrete consider one of the most important available technique and materials for construction in Egypt and all over the world. It is used in almost all structures as: buildings, shells, bridges, tunnels, tanks and retaining walls. Concrete is made by mixing binding materials as sand and gravel held together with a paste of cement and water. The use of admixture is to change certain characteristics of concrete such as workability, durability

  • Lateral Torsional Buckling Literature Review

    1403 Words  | 6 Pages

    Literature review Introduction Because of its importance in the design of steel beams, lateral torsional buckling continues to attract many researchers’ attention. Lateral torsional buckling is a limit-state of structural usefulness where the deformation of a beam changes mainly from in-plane deflection to a combination of lateral deflection and twisting while the load capacity of the beam remains constant, before dropping off due to large deflection. The main factors affecting the LTB are dimensions

  • Izod Pendulum Test

    1410 Words  | 6 Pages

    Polymeric materials for structural application sometimes undergo impact loads or rapid stress loading. There are a couple of test methods that can assess the ability of material to withstand such loads. Most common methods among them are Charpy and Izod impact tests in which Charpy test is generally used for metals whereas Izod test is very popular methods for polymeric materials [18]. The Izod pendulum test by which impact toughness is measured is described in the standard ASTM D 256. Average of

  • Vehicle Hynamic System Case Study

    718 Words  | 3 Pages

    In control system design the modeling of a dynamic system is important as it represents the behaviour and characteristics of the system being controlled. In vehicle dynamic studies, the mathematical modeling of vehicle dynamic motion is done based on physical laws that describe the forces and moment acting on the vehicle body and tyres. The vehicle mode with steering system is drawn in Fig. 1. The equations of Vehicle dynamics are as follows: m( ˙vy + vxγ) = (Fx 1 + Fx 2)sinδf + Fy 3 + Fy 4 +(Fy

  • Disadvantages Of Geosynthetics

    1489 Words  | 6 Pages

    3.1.5 Geo-Synthetic Material General Geosynthetics is the term used to describe a range of generally polymeric products used to solve civil engineering problems. The term is generally regarded to encompass eight main product categories: geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geofoam, geocells (cellular confinement) and geocomposites. The polymeric nature of the products makes them suitable for use in the ground where high levels of durability are required

  • Beam Deflection Theory

    1259 Words  | 6 Pages

    Abstract There are numerous types of beams that are fixed at either one or both ends such as supported, fixed, cantilever, truss, etc. With the aid of Abaqus, we can simulate the deflection of a simply supported bridge with a vehicle at the mid-span and obtain the maximum deflection from the simulated result. Manual calculation was also required to obtain the maximum deflection of the loaded bridge by using beam deflection theory. The span/deflection ratio must be within 200 to 400, and percentage

  • Preventive Teaching Analysis

    Formulating a definition of effective teaching, Goe, Bell and Little (2008) evaluated various discussions in the recent literature as well as in policy documents, standards and reports. They concluded that effective teachers have high expectations for all students and help students learn; they contribute to positive academic, attitudinal, and social outcomes for all students; they use resources to plan and structure engaging learning opportunities; they contribute to the development of classrooms

  • Essay On Discrimination In Sports

    799 Words  | 4 Pages

    “Female discrimination in sports is a common occurrence all around the world, women are seen as less than males.” (Ladrea) Equality in sports is unequal. In the 1800 women got very little attention and did not get the opportunity to play in any sport in America and all around the world. Men could go and try out for different sports teams and workout but for women they were only allowed to stay home to cook and clean. There were some events women could participate in but it could not be competitive

  • Spur Gear

    1571 Words  | 7 Pages

    In 1978, Cornell and Westervelt [36] provided a solution for dynamic model of spur gear systems which was valid for all contact ratios. The dynamic response of the gear system and the tooth loads and stress was obtained in this analysis. This dynamic model assumed two gears as a rigid inertia and the teeth were assumed as variable springs of a dynamic system which were excited by the meshing action of the gear teeth. The influence of various parameters like nonlinearity of the tooth pair stiffness

    3113 Words  | 13 Pages

    adopted the term Bio- Mechanics to describe the application of mechanical principles in the study of living organisms. As it was realized after 1950 that the mechanical principles involving the human body is entirely different from other things. When the study of mechanics is limited to living structure, especially the human body, it is called Bio-mechanics. The Bio-mechanics has derived from two words-Biomechanics. Bio means, something pertaining to living being or life. Mechanics means, the discipline

    Introduction to Fluid Mechanics Fluid mechanics is the branch of branch of physics that studies the mechanics of fluids (Liquids, gases and plasma) and the forces on them. Fluid mechanics can be divided into fluid statics, the study of fluid at rest; and fluid dynamics, the study of effect of forces on fluid motion. It is the branch of continuum mechanics, a subject that models matter without using the information that is made out of atoms; that is, it models matter from macroscopic viewpoint rather

    made ​​up of many individual collisions between gas molecules and between gas molecules and solid surfaces. In most applications, however, the aerodynamic nature of the molecular gases discrete omitted, and the flow field is assumed to behave as a continuum. This assumption allows fluid properties such as density and velocity, defined as everywhere in the flow. (III) Protection Act: Conservation of Mass: In fluid dynamics, the mathematical formulation of this principle is expressed as mass continuity
