Mystery Architecture B

Mystery Architecture B: At the beginning of the event, teams will be given a bag of building materials and instructions for designing and building a device that can be tested.

HI, I had a question on the arches and tunnels. Is there any information on what exactly is expected of these structures? For example, would the arches be free-standing, or as part of a bridge for example? If the primary dimension of the tunnel is the longest portion of covered part, then what is its base? Anyone have any ideas?

Second this question. After coaching this event last year, I am a hard time visualizing the structures for this year:

What is the difference between an ELEVATED bridge and last year? Is it that this year they are going to always add the hight to the primary measurement vs. just the length?
For the Arch, is this really the same as a bridge but measuring to the apex of the bottom supports?
For the Tunnel, I can't imagine how this may be run. Seems to me the only limiting factor is the "covering" that will be used to enclose the tunnel. But understand how this will be differentiated if there is no load.

Yes I know part of the challenge of the event are the unknows - but without having some understanding of the types of builds, it is very hard to practice and know what to learn.
Thanks for any insight.

Mystery Architecture B - cantilever fulcrum and counterbalance

Postby shri » November 18th, 2018, 5:00 pm

The rules manual says "If a cantilever is to be built, the event supervisor will supply the fulcrum, and provide a counterbalance." What are examples of a fulcrum and counterbalance? Would it be reasonable to practice with the edge of a table and a heavy book?

Mystery Architecture B - enclosed tunnel

Postby shri » November 18th, 2018, 5:02 pm

The rules manual says that for a tunnel, the Primary Dimension could be the measurement of the longest continuously enclosed portion of the tunnel. What does enclosed mean? If you are building with popsicle sticks, there are gaps between the sticks? Is that ok?

My plan for coaching this is to give them some kind of covering as well - either paper, a plastic bag or aluminum foil. Then we can measure the entire enclosed portion. I cannot think of another way this will work. And then to test it - maybe something like passing a ping pong ball attached to the end of a ruler through the tunnel.

Would love to hear other thoughts.

I guess that a edge of a table would be okay but I think that a heavy book is too heavy, maybe a phone?

Thanks for the response!
If the counterbalance is light, that already puts a bound on the length of the cantilever. If the objective is to build the longest cantilever that can bear the given loaded, I feel the weight of the counterbalance should not matter.

Ok so

- My team only meets once a week
- We've spent all our time in the meetings on build events
- Invitational in December

I'm thinking of practicing some Mystery Architecture builds at home so we don't crash and burn. What materials would I need, and how would I do it in general?

Ok, this is gonna be a long post... here goes...
Possible materials: Popsicle sticks, chopsticks, straws of all sizes, tape (remember that most Event Supervisors only give you small lengths, not the whole rolls), sheets of paper, string, cups, etc.
Of course, you don't know what they're gonna give you at competition. So you have to prepare for the unexpected. What my partner and I did was compile a list of different materials and categorize them. Below is the very basic list we used last year:

Attachment Materials: Thumb Tacks, Rubber Bands, Masking Tape, Scotch Tape, String, Paper Clips
Tier 1 Building Materials (10-25): Popsicle Sticks, No. 2 Pencils, Chopsticks, Slushy Straws, Bendy Straws
Tier 2 Building Materials (5-10): Paper Cups, Printer Paper, Notebook Paper
Tier 3 Building Materials (Miscellaneous): 1 Sheet Cardboard, 2 Paper Plates

We used a random spinner to choose one or two materials from each category. This way, we could guarantee that we had no practice sessions that only had all attachment materials. That would not be a good thing since it's pretty hard to build a structure with only tape, string, and rubber bands. Next, after identifying the materials we were gonna use, we used more random spinners to determine the quantity/amount of each material (for tape/string, select a length). Thus, we always had attachment materials and building materials every practice session, and they were pretty much always different.

Hope this answers your question, and I also hope this makes sense... ;) ;)

How will an arch be specified?

Postby shri » December 2nd, 2018, 9:36 pm

How will the primary dimension of an arch be defined an measured? This is the "sample task" in the rules manual.

For an arch, the Primary Dimension could be measured:
i. with no load, from the base to the highest point of the arch
ii. with a load, from the base to the highest point of the load

However, nothing in there differentiates it from a tower. I am thinking there will be some constraint that will require an architecture different from a tower. For example, I am thinking something like https://docs.google.com/drawings/d/1ToX ... sp=sharing where the goal will be to maximize the size of the red rectangle (without changing its width). Is this along the right lines?

Regards,
Shri

I think what defines an arch would be that there are two “areas” of suport with something connecting them and it can not touch the ground between two points that the event supervisor gives.

That is what I am thinking and coaching. Essentially a tower with only 2 sides on either end.
