down by combining a magnetic bearing with a hydrofoil. This allows the journal to be lifted clear of the top foil at start up and rundown then operated hydrodynamically once lift off speed has been exceeded. It also allows operation above the first bending critical speed by providing a method of increasing the stiffness and damping on request. The benefits of Air Foil Bearings over traditional bearings has driven recent developments in the technology as their use was initially limited to small‚ low

Introduction The task was given to obtain the buckling stresses for pin-ended steel struts of various slenderness ratios and compare with theoretical predictions obtained using the Euler and Rankine-Gordon equations. 2.

Using the same principle of Tyndell’s experiment—light reflection and refraction‚ in 1880 Graham Bell was able to use this device to transmit a sound through a beam of light. Graham Bell and his assistant used a sensitive selenium crystal and a

into beams making it easier for captains to see the shore lines before it was too late. The shape of a lens makes a big difference. The lens is a transparent piece of glass or plastic with at least one curved surface. There are two types of lenses used today‚ the convex lens‚ which is also commonly called the positive lens‚ and the concave lens. The glass or plastic surfaces of the convex lens bulge outwards in the center. This lens also makes a parallel light ray which passes through bending it

optimum design of the wing‚ there are several assumptions are made‚ The wing root thickness is 12% of the chord. The contribution of the auxiliary spar is neglected. The spar can be treated as tension field beam. The stringer/skin can contribute up to 50% of the bending moment‚ but the bending moment contribution of spar remains 100% because of safety. The material for the entire wing structure is AL2024-T3. The compressive strength of the material is equal to tensile strength of the material.

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 clear

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
