Fettuccine Truss Bridge
Introduction
Fettuccine Truss Bridge
Introduction
Truss is a structure built up of three or more members which are normally considered being pinned and
hinged at the joints. The following figure shows different types of trusses. Load applied to the truss is
transmitted to joint so that each individual members are in either pure tension or compression.
Objectives
To develop student’s understanding of tension and compressive strength of construction materials
To develop student’s understanding of force distribution in a truss
To design a perfect truss bridge which fulfils the following criterias:
*High level of aesthetic value and Minimal construction material
Task
In a group, you are required to design and construct a fettucini bridge of 350mm clear span and maximum weight of 80g. These requirements are to be met, or else it may result in reduction of grade. The bridge will be then tested to fail.
Other than aesthetic value, the design of the bridge must be of high efficiency, i.e. using the least material to sustain the higher load.

Other than aesthetic value, the design of the bridge must be of high efficiency, i.e. using the least material to sustain the higher load.
In order to achieve higher efficiency, you need to analyse and evaluate each of the following items.
- Material strength
- By adopting appropriate method, determine the strength of fettucini, i.e. tension and compression strength
- By knowing the strength of fettucini, you will be able to determine which members to be strengthened
Structural analysis of the truss- Perform detailed structural analysis of the truss o Identify critical members- Strengthened the critical members if necessary

Reflection
This project is very interesting despite very challenging as it is my first time to actually use fettuccine to build a model. For this project we working on a bridge model as we have to test everytime we are done with a model to see how much weight it can hold until it breaks. It gives me an excitement to improve our model after every failure and I've learnt to not give up so easily. Calculation wise was very tough as well but it gave me a very good understanding on the entire bridge and from there we can actually know how to calculate and also built the bridge to maximise its sustainability.
