The goals of this project were to find a way to build a truss that could withstand a large amount of weight the more weight the better. We wanted it to withstand the pressure but we wanted the truss to not break so quickly, we didn't want it to just snap in half at the weight of the pressure. We additionally didn't want there to be a whole lot of space in between the wooden pieces otherwise they would break easier because the father apart the more likely it would be that weight would not distribute right, that also brings up making sure our weight is evenly distributed among the wooden bars.
Generate Concepts
The breaking point was expected because as I pointed out what we didn't want to do, we did, we put more weight on one side causing it to push more weight on that side. Meaning it will break on the longer wooden pole. We decided on this one though because it had the least amount of separating in between the two different triangles, but we also thought this could with stand more pressure then the other designs.
Unfortunately I was not there for most of the project so I do not have all the information that is needed for this too look correctly. Or how my weebly's usually look. I had determined that this truss is statically determinate, but the most amount of weight actually goes to bc which is the shorter side of the triangle.
Develop a Solution + Construct and Test Prototype
I don't have all the information I would like to put on here because I was absent for pretty much all this project and have spinets of this project. I have my calculations for the first truss which is statically determined but for the second truss they gave me the information for the truss but when trying to solve it I got that it was not statically determinate. So I don't have the calculations for the second truss on one note.
Evaluate Solution
I don't have the efficiency evaluation for all three, I had no idea this was needed and was only give the two trusses. But I do think the second truss is the best because it can withstand the most amount of pressure. It was able to withstand longer then the first one. It was also more distributed then our first one.
Present A Solution
In this picture max is aligning the truss we made then starting to put it together.
Max is measuring to make sure the measurements are how we want them to be and are correct.
Putting all the measured pieces together to make our truss.
Conclusion
I thought it would break where it was breaking because it was the longest piece and would withstand the most amount of pressure because it wasn't evenly distributed, but our calculations and mdsolids tells us the opposite member holds the most amount of pressure. I would make it more evenly distributed and if we could expand the project beyond I put more support staff on it because there wasn't enough behind it.
