TYPES OF STRESS

- One type of stress is structual stress

BRIDGE DESIGN
- Our design is to put triangles on the side to support the bridge
- We will also put posicle sticks on the bottom for more support
- We will also glue posicle sticks to the edges of the triangles
CONCLUSION
- Our conclusion was that our bridge didnt hold at all and it fell and broke
- If we were to ever do this again we would put more support on the edges so that it could at least hold up and it would last.
