During our engineering and technology studies we were given the task to construct a bridge or a tower that would demonstrate our understanding of load distributions and strength to weight ratios. I opted to go for a tower based on the designs of the John Hancock Centre and the Willis Tower. I wanted to use the cross bracing on the outer walls of the structure for effective load distribution, with the stepped roof climbing up to the centre of the tower. These two elements combined created an elegant and structurally sound tower. I used lightweight balsa wood, laser cut to ensure consistency, and ultra strong balsa cement for bonding. The towers were tested until destruction to calculate the strength to weight ratio.
