The frame is 3 metres wide and 6m long (the frame length is in the same direction as the vehicle length). The frame consists of roof sheeting, which is connected to 15 rafters of length 3 metres, which are supported by 2 beams of length 6m. The exterior beam is supported by 3 columns of height 3m (i.e. 3m from the ground to the top of the column), and the interior beam is connected to a building. All elements are made from timber. The roof sheeting is 40 millimetres thick. Cross-section dimensions of columns = 150mm x 150mm Cross-section dimensions of rafters and beams = 150mm x 50mm (the vertical dimension is 150mm) Density of all timber and roof sheeting = 700kg/m3 and E = 15GPa Live load on the roof = 3 kPa Strength of the soil at the site = 200kPa. Calculate the strength of the column timber material required for the column loads applied.
