Week 4 constructing journal This week’s tutorial, we did go for the workshop for practicing using the real tool to make the structure. To match the one meter long span, the structure we made have to be longer than one meter. As the plywood is very flexible and is able to make the structure stable, we placed the plywood to cover the battens. Mark tools have to be used for cutting the right angle of the battens. To make the structure be more stable, we cut the one of the battens into pieces, then placed them onto the other two battens to be the beams to support the loads of the structure. To combine them together, nails have to be used. We first thought that we could cut one of the battens to insert it into the other part of the batten to make the kind of much stable structure. But as the time was limited and to make the complex stable structure must cause the most working time, we did not have enough time to finish making another structure, therefore, we gave up. But we still use the limited time to finish making the easy but stable structure.
When we destroyed this structure, we found that when the force was around 280kg, the middle part of left batten was broken and it was at the nail’s position. According to this, we can easily find that the softest part of the structure might be the point of the connections such as the position of the nail. Actually, what I think is that for those group who use the truss to be the main structure of the construction, this kind of structure must be more stable because they make the structure as the whole part. For example, they cut half of the batten and insert the remaining part into it, this kind of job make the structure to be a whole part and let the structure be much more stable.
