# A high school project including constructing a bridge that would withstand a very good amount of wei

Transportation Engineer Have you ever visited family members for the holidays.

Read more Variations How do material properties affect the strength of the bridge. No links to playlists or to channel pages. When the bridge fails, weigh the container.

B Fold the clear tape over Straw 1. Cut the supports to whatever length best fits the truss. Applied load divided by the material area it is acting on. E is another example of what knots can look like.

The schematic shows you exactly where each piece needs to go. Video playback can be helpful here, if you have a video camera.

You might have started your trip by taking the subway or a train to the airport. Calculate the strength-to-weight ratio of the bridge by dividing the mass it took to break the bridge by the mass of the bridge itself, as shown in Equation 1.

If the video description says: There are floors in the Sears Tower. Because a certain amount of time is needed for hydration to completely occur, concrete members do not gain their full strength until much time has passed. It is important that the bridge's sides are parallel to each other and perpendicular to the floor.

Then assemble the sides of the bridge, let the glue dry and remove clamps. Concrete for foundations and anchoring, steel for beams and cables, etc. Other types of materials are not as commonly used as steel and concrete.

The many types of steel are called alloys. Another challenge for geotechnical engineers is building structures on slopes or hills. A rock that contains a high concentration of iron.

A building fails when it falls over or even when it starts to lean, like the Leaning Tower of Pisa. Simply deleting your post may cause the spam filter to catch future ones.

Steel is a ductile material and it yields or deflects before failure. Baiting users into breaking this rule is not allowed. Can you identify which part s of the bridge failed first.

Use two clips per cross support, one at each end.

Audio over a static image or slideshow may also violate Rule 0. E For attaching top and bottom cross pieces, use a medium binder clip to clamp around the cross piece and chord.

Concrete is also extremely strong in compression. Many of these construction projects are "public works," meaning they strengthen and benefit a community, state, or the nation. This is grounds for an immediate and likely permanent ban, so consider this your only warning.

You will investigate how deep you have to dig the foundation for each angle of slope. Santa Barbara education professor Russ Rumberger.

If the video has a watermark, it also may be licensed by a third party. If you tape pieces too tightly, then parts of the bridge may not lay flat. This includes videos of child and animal abuse. Stone is only useful in handling compression forces and therefore is most often used in arch bridges.

Take ideas from students, write them on the board. The diagonal supports in the truss see Figure 9 will probably need to be cut to a slightly different length than the ideal length given in the bridge schematic. Who decided the position of the airport runway?.

Partial Design Process These resources engage students in some of the steps in the engineering design process, but do not have them complete the full process.

While some of these resources may focus heavily on the brainstorm and design steps, others may emphasize the testing and analysis phases.

PROBLEM PROJECT: TOOTHPICK BRIDGE DUE: Friday, October 24, (Start your project early. This one will take time) PROBLEM Design a bridging structure that will span a gap of cm and withstand a load of grams.

"Building Model Bridges Following the Engineering Process" is a curriculum unit designed to be used with students in grades 5 through 8.

I am a Magnet School Facilitator at East Rock Global Magnet School where I run an after school program called CPEP. A project vision is an image a project team holds in common about how the project will look upon completion, how they will work together, and how customers will accept the project.

True Everyone on the project team should have identically the same vision of the project. This structure is very good at resisting wind loads.

civil engineering: The field of engineering pertaining to non-moving structures such as roads, sewers, towers, buildings and bridges. deflection: The amount a structure bends or moves from its "at rest" position. The Golden Gate, Brooklyn Bridge and the Tacoma Narrows Bridge are a good start.

The Narrows Bridge art deco towers are 50 ft wide at the base and 39 feet wide across the top. Research the height and draw a diagram to scale.
