Our team designed a balsa beam structure to carry a 2.5kg static load over 400mm. We created an I-beam design with vertical and horizontal balsa supports added to the wood sheet. This design strengthened the beam while using minimal materials. Upon testing, our beam deflected 1.1mm under load, meeting the criteria. In reflection, we found our design and fabrication worked well but could be improved by reducing materials usage and modifying the wood sheet for increased rigidity.
