    CMSA is a non-profit forest industry association providing inspection and education services in relation to lumber quality standards in BC’s forest products companies. Mr. Beatty was on the board of directors and held the position of Executive Director responsible for overseeing the management of the daily activities of CMSA which consisted of a small staff of management and administrative staff. As well, he was responsible for maintaining the client relationships with the companies who used CMSA’s services and was responsible for overseeing the formulization of the annual budget and its presentation to the board of directors. It should be noted that before the CMSA’s creation, there was a similar organization called the Council of Forest Industries (COFI) which provided the same type of services that the CMSA grew out of this organization. Mr. Beatty was initially employed by COFI before CMSA and his term of employment with CMSA included his term with COFI – 11 ½ years total.…

    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.…
