CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY Reinforced concrete is a strong‚ durable material that can be formed in too many varied shapes and sizes ranging from a simple rectangle column‚ to a slender curved dome or shell‚ its utility and versatility are achieved by combining the best features of concrete and steel. Its utility and versatility is achieved by combining the best features of concrete and steel. When combined‚ the steel is able to provide the tensile strength and probably

Integrated Mechanical Testing Laboratory BUCKLING OF A COLUMN Objective The primary purpose of this experiment is to verify the critical load for buckling‚ relationship among the bending-moment and deflections‚ for different end conditions when a rectangular beam is subjected to axial loading. Theory A column is a member subjected to axial compressive forces. When a column is concentrically loaded‚ it is expected to reach its yield stress. But usually prior to yielding

CHAPTER 7 WATER TANK 7.1 INTRODUCTION As per Greek philosopher Thales‚ “Water is the source of every creation.” In day to day life one cannot live without water. Therefore water needs to be stored for daily use. Over head water tank and underground water reservoir is the most effective storing facilities used for domestic or even industrial purpose. Depending upon the location of the tank the tanks can be named as overhead‚ on ground or underground. The tanks can be made in different shapes

It has been necessary to research designs‚ types of wood‚ and types of adhesive that will create a final result that is consistent with the desired result. Literature Review: The design concept behind a cantilever truss consists of a series of triangles joined together. The strength of these individual triangles‚ when combined‚ creates a very strong final result. Triangles are a very important part of many types of construction as they are the “only geometric

3.4 Thermal Effect Shear strain In general‚ increase in temperature causes the atoms to vibrate more and makes average atomic spacing greater. Macroscopically‚ this will lead to dimension increase in solid: T + T +V T – T – V In an isotropic material‚ temperature change only introduces variation of direct (normal) strain. In other words‚ thermal deformation does not cause shear strain. where T0 is a reference temperature and = coefficient of thermal expansion (C)-1 Hooke’s

reinforcement of the cantilever beam did not have any development into the pier itself which caused the shear itself. The launching girder has failed due to the failure of the pier cap. This failure also caused the span between piers 67 and 68 causing it to be inclined supported by the ground on one end and the pier cap on the other. With the failure of the pier cap and span between piers the crane used for lifting the launching girder also failed on July 13th 2009. Bending of the crane shows the

CHAPTER 1 INTRODUCTION Rotor dynamics is the study of rotating machines and has a very important part to play throughout the modern industrial world. Rotating machinery is used in many applications such as Turbo machinery‚ Power stations‚ Machine tools‚ Medical equipment‚ etc. Failure of machinery in applications such as aero engines‚ turbo-machines‚ space vehicles‚ etc. creates enormous repair costs and more importunately may put human life in danger. Rotor dynamics is a collective terms for

Intermediate and end loads were place on the sample and the strain was measured at various distances from the loads. Using the dataset from the individual loads‚ the superposition strain was calculated and agreed within 7% of the experimental strain with both loads. From the measured deflection of the cantilever beam and the dataset‚ Young’s Modulus for the aluminum sample was determined to be
