Former Northwood Contestants: some great, some good, and some not-so-good. Held over 100 pounds. Excellent design and craftmanship.

Simple, good design, scored pretty well.

Violation: Bridge length too short, extensions added to meet code requirements. Bridge performed poorly.

Violation: Laminated, bridge disqualified,

Lacks symmetry and balance, bridge performed poorly.

Ok design, performed decently.

Excellent craftmenship and design. Performed well.

Very good truss design and craftmanship.

Poor craftmenship, lacks symmetry.

Extremely heavy, overall poor engineering efficiency.

Good design, performed well but lacked symmetry.

Good example of an under-hang. Scored pretty well.

Good design, little heavy, good performance.

Good design, performed well, used several design components from different bridge types.

Examples of blue prints: ==

Use your blue prints as a template for cutting your pieces:

Then use a copy of your blue prints to lay out all your pieces:

Place wax paper over your plans. Then use the protected plans to begin gluing/assembling the individual pieces to your bridge. Pins can be to hold pieces in place until they dry.

Soon you will be done:)

Some cutting tips. Maximize the amount of surface area when attaching/gluing pieces together.

Think outside the box for solutions.

Have fun!



and then mourn the destruction (testing) of all your hard work:)
