PT1.1 - Engineering Goals

Problem statement: 

Using only ice cream sticks and glue, design and construct a bridge which display high structural efficiency.

Efficiency: Mass of load supported in grams/ Mass of bridge in grams


1. The model bridge may be constructed from standard sized ice-cream sticks only. No other material is

    The dimensions of the standard sized ice-cream sticks:
    Length: 113 mm Width: 10 mm Thickness 2 mm 

2. The ice-cream sticks may be cut or joined in any fashion. Joining may be done with any commonly
    available adhesive / glue only. No other material, i.e. string, tape, wire, nails etc, is allowed. 

3. The bridge may be stained, painted or coated in any fashion. 

4. The bridge must have a length between 550 mm and 650 mm, a maximum width of 120mm, a maximum
    height of 200 mm and a maximum weight of 500g

5. The load will be applied downward using a loading bar placed across the centre of the deck and masses will
    be supported on a suspended vertical loading rod.

6. To simulate a real-life bridge, the model bridge must have a deck for motor vehicles to travel on. 

7. The bridge must be constructed to allow for the loading bar to be placed across the centre of the deck. 

8. Loading will stop once bridge failure occurs. Bridge failure is defined as the inability of the bridge to 
    carry additional load with any member of the bridge breaking, or total collapse whichever occurs first. 

Group goals:

1. Built a bridge that is able to withstand 50kg
2. Built a bridge that has a mass that is lower than 400g
3. To reach an efficiency rating of more than 200
