The Factors Affecting the Deflection of a Spaghetti Bridge


An Investigation into the Factors Affecting the Deflection of a
Spaghetti Bridge - Planning

* Preliminary Work

I have decided to investigate how different masses affect the
deflection of a spaghetti bridge. We have been given a selection of
different types of spaghetti. To find the type that will give me the
largest range of results I need to test each type to find the one with
the largest breaking force.

To do this I held the spaghetti in two clamp stands (one at each end
of the strand) and then applied a mass to the centre of the spaghetti.
Starting at 10g and increasing the mass by 10g each time. Each type of
spaghetti was cut to the same length of 20cm. I found that the
"Waitrose Italian Spaghetti" had the largest breaking force of
approximately 90g.

I predict that the deflection of the spaghetti bridge will increase
proportionally to the mass applied. I believe this because spaghetti
is an elastic material (it will return to its original shape when a
force is applied) and Hooke's law states that for elastic substances
the extension (deflection) is directly proportional to the stretching
force (mass applied). However, all materials have an elastic limit
(when too much mass is applied then it will no longer return to its
original shape) and will break. If the elastic limit is exceeded then
the deflection in no longer proportional to the mass applied.

* Investigation

* Hold a piece of Waitrose Italian Spaghetti in two clamp stands.
Position them so the distance between the place where the spaghetti is
attached is 20cm.

* Find the mid point ...

... future I would attach
the mass to the spaghetti using cotton thread tied tightly so it would
not move.

To improve the experiment I would find a more accurate way of
measuring the deflection. Since using a millimetre marked ruler was
cumbersome and the spaghetti was more than 1mm thick therefore it was
difficult to decide where to measure the deflection from. I would also
find a way of preventing the ruler and hanging mass from interfering
with each other since they got in each others way during the
investigation.

Additional work, which could be carried out, is to repeat the
experiment using, a wider range of lengths of spaghetti. The
investigation could also be extended to investigate other factors
affecting the deflection such as number of strands of spaghetti,
thickness of spaghetti or type of spaghetti.

The Design Of The Bridge Essay

- A bridge is a structure ,built by many different materials, to travel over physical objects. For example, bridges were made over bodies of water, roads or intersections, and valleys. The first welded road bridge was designed by Polish engineer Stefan Bryla in 1927.There is an average of about 607,380 bridges throughout the Unites States. There are many different bridges throughout the world and there is also different causes for bridges. There are also many different designs that all have different purposes and apply to different situations....   [tags: Bridge, Bridges, Box girder bridge]

Essay on Design A Bridge And Its Effect On The Bridge

- Introduction A bridge is required to span a gorge in New Guinea. The goal of this project is to design a bridge that meets the requirements for that bridge and then construct and test that bridge on a 1:20 scale. The requirements for the bridge are that it has to span across the 600mm (12m to scale) wide gorge which has two square flat areas on either side of the bridge which are 100mm (2m to scale) wide. The bridge must be able to hold the maximum possible weight while remaining as light as possible....   [tags: Bridge, Truss, Truss bridge, Covered bridge]

For example, a beam bridge’s weakness would be that you have to use a lot of stone starting up from the ground. Another example would be how a suspension bridge’s strength would be it flexibility, like the Golden Gate Bridge. The engineering process for a bridge would be to first make sure everything will be symmetrical. Secondly, from that symmetrical blueprint, the construction of the bridge is now good to go....   [tags: Bridge, Bridges, Alameda, California]

The San Francisco-Oakland Bay Bridge Essay

- About eighty years ago, engineers were able to build a bridge on time and within budget with no problem; today, most of the projects take extra time and money to finish. What exactly happened between now and eighty years ago that caused such a drastic shift. It is clearly not the engineers nor the technology; in fact, those have only improved over time. Today, engineers are faced with much more than designing and building the infrastructure, as they were before. They compete with politicians for funds, fight for the safety of workers, and protect our environment by adhering to the numerous laws and acts set forth by the government....   [tags: Transportation, bridge]

Suspension Bridge at Location D Essay examples

- ... Suspension bridges are visually appealing and light yet strong and durable. Suspension bridges are made from enormous cables that reach from one end of the bridge to the other. These cables rest on top of high towers and swoop down. They are fastened by anchorages that are on both ends of the bridge, which help stabilize the bridge. Most of the weight of the bridge is carried by wires that drop to the road surface from the main cables. These wires help evenly allocate the weight of the bridge and keep the cables sturdily in place....   [tags: bridge, ocean, distance]

Leones Spaghetti Essay

- Leone’s Spaghetti The “spaghetti” western, Sergio Leone’s conscious departure from what had come to be known as the “classic” western formula, became a modification of the conventions of the traditional genre. In the film For A Few Dollars More (Per qualque dollaro in più, 1965), Leone’s formula is developed through a reformed narrative structure, slight changes in the traditional characters, his unique style, and the simple use of language, which revolutionized the western. The American “classic” western formula, according to Peter Bondanella in his essay A Fistful of Pasta: Sergio Leone and the Spaghetti Western, employed “a combination of narrative possibilities generated by three c...   [tags: essays research papers fc]
