transportation. Whether it’s a canyon‚ or a body of water‚ bridges allow travel over those gaps from one part of land to the other. The world would be forever changed without bridges. The five main types of bridges are arch bridges‚ truss bridges‚ beam bridges‚ suspension‚ and cable-stayed bridges. Arch bridges are bridges that use arch as a main structural support/component. Depending on how much weight is normally being applied on the bridge‚ they are made with one or more hinges. One of the more

Africa and Asia‚ building bridges and roads of very high quality. 2- Different types of bridge designs (include diagrams and labels) The beam bridge... consists of a horizontal beam supported at each end by piers. The weight of the beam pushes straight down on the piers. The farther apart its piers‚ the weaker the beam becomes. This is why beam bridges rarely span more than 250 feet. The truss bridge... consists of an assembly of triangles. Truss bridges are commonly made

disaster. It becomes increasingly easy to say each time‚ permitting more and more untruths into the relationship. These bolstered white lies soon begin to take the form of deflection‚ omission‚ stereotyping‚ out-and-out lies‚ dismissal and delusion; all upper-class lies that we never thought we would commit. Nevertheless‚ by simply telling my girlfriend that one white lie‚ I immediately join a higher order of lying. Is it not stereotyping and cliché to think that a girl only wants to hear that she is

12 March 2003; accepted 18 March 2003 Abstract This paper presents a detailed numerical study of the mode I interlaminar fracture of carbon/epoxy composite laminates with z-fibre reinforcement. The study was performed using a double cantilever beam configuration. A finite element model was developed using thick-layered shell elements to model the composite laminates and non-linear interface elements to simulate the through thickness reinforcements. An existing micro-mechanical solution was employed
