- In the above figure, if you are going to suspend the 100 pound weight
in the air then you have to apply an upward force of 100 pounds to the
rope. If the rope is 100 feet (30.5 meters) long and you want to lift
the weight up 100 feet, you have to pull in 100 feet of rope to do it.

- The goal of Destination
Imagination is to encourage kids to learn, stretch themselves and have
fun. Kids that really enjoy the
Structure Challenge will begin to see the “structure” in everything
around them. They will wonder WHY
things they see are designed the way they are. They will also be able to recognize
and admire the “design elegance” they see in natural structures. This awareness, appreciation and
curiosity is perhaps the greatest benefit this Challenge has to offer.

- There are many tools for cutting and forming material, nearly all of
them are very sharp!
- Sharp edges should always be directed away from the flesh.
- Wear eye protection while cutting and shaping things.
- Always work in a well ventilated area.
|
|
19
|
- Sharp tools such as razors and x-acto knifes (used extensively for
balsa) are commonly used for this type of problem. When any sharp tool is used, sharp
edges should always be directed away from flesh
- Let team members experiment with cutting, breaking and sanding wood
with various tools (including a razor saw, such as x-acto makes)
(encourage them to explore any tool they think will allow them to build
better/easier.)
- A Razor Saw can be use with a mini-mitre box to make “square” cuts.
Examine cuts under a magnifying glass to make sure your saw/blade is
not crushing the wood during the
cutting process. Strong
joints require clean cuts.

- A large open table with lots of overhead light, where team can place
building jigs, weigh wood, saw wood, assemble, & finish structures.
- Cover the table top (sheet of thick plastic or masonite) (unless you
like glue and scratch marks to give it that antique look).
- Access to ventilation (kitchen exhaust fans are ideal) in case of glue
fumes.
- A computer is ideal for drawing straight designs (snap to grid) and
keeping track of designs
- If not, Graph Paper, rulers, pencils, squares and protractors are handy
to have.

- Glue Selection is an important aspect of the team’s solution. It’s not Interference to buy an
assortment of glues to let them experiment for strength and
weight. But let the team make
the final selections for the structure.
- Factors in the selection will include drying time, strength, weight,
ease of use.
- Remind the team to read glue directions for best results.
- Super glues need good fitting joints to be effective. Get them to think hard about the
contacting surfaces.
- Ask the team to break apart the joints to see what breaks (glue or
wood)
- Have the teams consider the following before making their choice
- Can the glue be used safely?
- How strong is the joint created with the glue?
- How easy is it to create a joint with the glue?
- How consistent are the joints created with the glue?
- How long does the glue take to “set”
- How much weight does the glue add to the structure?

- There are many species of wood available
- Have team members experiment with a variety of woods.

- Sources for basic design ideas
- Any book/s with picture of structures (water tower, antennas, watch
towers, cell telephone towers, power line tower, etc, bridges,
etc.) Take them on field trips.
- Introductory structure books (see list)
- Small scale experiments
- Construct structures out of soda straws and tape to hold up books
- Some teams even use K-nex

- Plans
- Always build to a plan (computer drawings of side views are one
example)
- Team manager should encourage team to brainstorm alternate assembly
orders/processes. However team
decides which they like best.
- Allows them to keep records of design and performance.
- Reproducibility
- It would be Interference for a Team Manager to insist the team use a
jig, but it is OK, to expose them to the concept of jigs. Construction
Jigs are used to hold pieces in place until glues set. Jigs can be:
- * Simple foam squares (thick pink
insulation) Pin drawing to foam
(Dress T-pins are easy to use), pin wood to drawing
- * Metal background and magnets to hold
pieces
- * Custom wooden frame jigs
- Have a team brainstorm on ways to improve jigs as their designs mature
- Teams must build the jigs that they use

- Strength
- Buckling is a failure
mechanism where long thin members loaded in compression end up “bowing”
(& eventually breaking) near the middle. (Depends on length,
cross-section and material properties)
- Stability
- Many structures “Fail” because
they start to lean – and the leaning loads one side of the structure
more than the other.
- Manufacturability
- Consider building simpler
designs first (save the complex ones for later after they’ve gained some
experience)
- Finish Details
- Stay close to the design
- Make sure all the joints are
good (structure is as good as its weakest joint)
|

|
- The Grand Finale of a Structure Problem begins with Weight Placement
- The order in which weights are placed, the positioning of the weights
and even such details as the hand positioning of the people placing
weights can impact the stresses the structure experiences.
- Plan and Brainstorm contingencies
- Practice, Practice, Practice…So there are no “Snap” decisions

- The Prep Area Appraiser (All Team Challenge Sites)
- The Prep Area
Appraiser will:
- 1. Greet your team and Team Manager(s)
- 2. Collect and check all required items, such as paperwork and props
- 3. Tell you all about the Presentation Site and the Appraisal Team
- 4. Answer any questions you have and take care of you until it’s time
for you to present your solution
- The Team Challenge
Appraiser
- The Team Challenge Appraiser evaluates some or all of the required
things in your team’s Challenge, including the Side Trips. Usually there
are at least three Appraisers doing this job. After your Presentation,
these Appraisers will come and talk to your team about what they have seen
and heard you do. Be sure to show them and tell them about the things of
which you are proudest.
|

|
- The Instant Challenge
Appraiser
There will be at least two or three Instant Challenge Appraisers for
each Instant Challenge site. The Appraisers will score your team based
on how well you solve your Challenge. Instant Challenge Appraisers are
VERY friendly and they love to watch your team work on a solution.
|
|

|
- For the On Safari Challenge, there are two special Appraisers.
- 1. The Prep Area Appraiser for Check-In will check your team in before
you go into the StuDIo, and make sure you have all the items you need to
solve your Improv Challenge. The Prep Area Appraiser for Check-In will
introduce you to the StuDIo Supervisor.
- The Studio Supervisor will take you to your StuDIo, let you randomly
select your choices, and watch your team work on its solution. The
StuDIo Supervisor will not actually be scoring you in terms of points,
but he/she will write down some friendly comments about how your team
works together.

- Inside DImension Teams:
- The Structure Check-In Appraiser
- For the Inside DImension Challenge, there is a special Appraiser. The Structure
Check-In Appraiser will examine your Structures, measure them and weigh
them, and make sure they are in keeping with the guidelines in the
Challenge. Before your team goes to the Prep Area for Inside DImension,
you MUST have your Structures checked.
