... which the structure may be attached. Designs Considered: The main design considered apart from the 4 main member triangulated cantilever, was based around a 3 main member design with cross bracing shown in the diagram to the right. The advantage of this structure is a reduction in weight, holes and rivets thus a huge reduction in cost. However, the design that we came up with was too difficult to analyse and predict during in failure, due to the side planes not being vertical. Also, construction would have been quite difficult because all cross braces would have to attach to the main members at an angle, thus additional plates would have be constructed which would have raised the price dramatically. The other design considered was based on the 4 main member design but flipped upside down. However, this would mean that the compression member would be comparatively long, increasing the need for cross bracing ...
