The Queen Post Truss: The Truss of Beauty
The Queen Post truss is very similar to the Kings Post truss in that it does not take much material; therefore it takes less money to construct. The Queen Post truss is also more stable than the Kings Post truss as well as more elegant. It's not only simple, but its one added beam and square shape truss rather than a triangular shape makes it much easier on the eyes. The Queen Post truss is primary used to stabilize short spans. So although the Queen Post truss doesn't give as much span as the Kings Post truss, it's still a simple, elegant choice for those with less space.
Details
As opposed to the Kings Post truss, the Queens Post truss is a square truss. The Kings Post truss has two diagonal beams of either metal or wood and is connected by a chord to a single vertical beam. The Queens Post, however, has two diagonal beams with a vertical beam at either side of the end of the diagonal at the top of the roof. The final beam is a horizontal beam of thicker metal or wood, holding all the chords for the other two diagonal beams and two vertical beams.
This model of truss is ideal for those with less space and a little more money to spend. Although elegant, the Queens Post truss does have two more beams than the Kings Post truss. Although, if you're already spending the money for a truss in general, two beams and a different shaped truss can make all the difference style-wise for a small fraction more. The square shape of the Queen Post truss is more widely known than the triangular shape of the Kings Post truss because the triangle is seen as a more abstract shape than a square since the square is equal on all sides.
The Queens Post truss can also be used on many bridges. Since the chords holding the tension and weight are all on the horizontal top beam, it is very important to make sure that when constructing a Queen Post truss, the horizontal beam is a great deal thicker than the diagonal and vertical beams. The Queen Post truss is often used on shorter bridges and often time is favored on shorter bridges than the Kings Post Truss. As previously stated, the Queen Post truss does have two more beams than the Kings Post truss, so it is more slightly expensive but is much more favorable in modern day architecture than the Kings Post truss.
Many people find trusses in general a very scary ordeal. Hiring architectures and carpenters can be a pain. The Queen Post truss is one of the easier models of trusses to construct and takes a shorter time than many other complicated trusses. The square shape of the Queen Post truss is incredibly appealing. I would most definitely suggest a Queen Post truss for your future home improvements if you have a small space, small budget and want something beautiful!

Balsa Wood Truss that can hold 10 pounds?
So in my engineering class, we have to build a 12in truss out of balsa wood that can hold 10 pounds. The amount of wood we can use 12ft, we can't stack them, and they are are extremely flimsy rods. We can only use the wood given and super glue. We also have to do the math for how much wieght is on each point of the truss. What I would like to know is what is the best way to build this, and angles to use? (My partner and I are doing a warren truss, with a piece of wood through the middle, and more triangles on the bottom part)
also, which area of the truss should we put weight on?
The optimal height of a model truss bridge is 1/6 of it's length. So for a 12inch long bridge, your bridge only needs to be 2 inches tall. However, I would suggest that you make your bridge 3 inches tall. When you increase the height of the bridge, it decreases the forces on the top and bottom chords of your truss. This will be good for you because you are given only
I would recommend using a Warren Truss with Vertical supports. This means that in addition to the triangles that make up your truss, you add vertical members to look like this: /||/||/|. As far as the angles, what you are looking for is each triangle to only be 2 inches wide.
The vertical members will break the top and bottom chords up into smaller sections. A shorter length is especially good for the top chord, which will be under compression. Wood loses strength in compression the longer it gets. So by adding those vertical pieces you decrease the length of the sections of your top chord, which will make it stronger.
Make sure that you include lateral bracing on your bridge. This is the X's that join the two sides of the bridge together. This is super important to the stability of your bridge, and its ability to resist twisting forces.
For loading the bridge, I would put it in the very center. If you have any wood left over, then you can reinforce the center portion of your bridge.
