    The shear stress distributing in a beam depends on how Q/b varies as a function of y1. For a beam with a rectangular cross sectional area, subjected to a shear force V and a bending moment M. as a result of the bending moment a normal stress is developed on a cross section, which is compression above the neutral axis and it is tension below the neutral axis. To investigate the shear stress at a distance y1 above the neutral axis. Then dA=bdy, so equation 2 becomes…

    This type of truss is similar to the Warren truss but the difference is that the structure is below the roadway. So it requires a few amounts of materials, is light weight, easy to build, usually build offsite therefore quick to build, better more open view o n top and is also economical. The top part of the truss is in compression were as the bottom part is in tension. The interior members alternate between tension and compression to keep a stable structure. This type was first built after the design of deck bridges around 1800.…

    An investigation into beam bending and superposition. Being able to analyse how beams bend is an essential tool for all engineers. By using mathematics and material properties, engineers are able to compute structural deformation thus verifying a structures fitness for use. In this experiment a simply supported beam of aluminium is loaded with point forces in three different cases. A clock gauge is positioned in the middle of the beam to measure the deflection. The results of a complex arrangement of forces can be deduced by the superposition of more simple cases. Superposition is possible only when the response of the structure is linear, e.g. when deflection is directly proportional to the applied load. Also the experimental and theoretical deflections of the beam will be compared and a percentage error obtained. There was a second test performed in this investigation demonstrating the influence the 2nd moment of area, also known as the second moment of inertia, had on the load carrying capacity of the beam. The results from test 1 show that it is possible to deduce the deflection of the beam when loaded with point forces by superposition. Results from test 2 show that the deflection of a beam is influenced greatly by its moment of inertia, i.e. with a greater value of inertia there is a smaller deflection.…

    Rosewood extraction methods are also incredibly inefficient. Due to the ever growing need to go farther into the forests, loggers are finding themselves further from the coast. Thus, for every rosewood tree obtained, four or five more buoyant trees are harvested to build a raft for the rosewood log (Global Witness & Environmental Investigation Agency, 2010). This furthers aridification of the landscape, reducing local species diversity and produces an increased probability of forest fires.…
