Objective : Design a structure to survive under the earthquake.

Challenge $1$: Design a structure to swive under the earthquake.

In this challenge, each group shall design a structure on the moving plate as following.

$$

Your designed structure will be placed on the top of this moving plate and will be operated such as the earthquake.

Score: When your structure stays on the plate more than $10sec,$ it will pass

There are $5$ levels of the vibration of the plate.

$3$ pts for each level.

Total $15pts$

Challenge $2$: Design a structure to save people under the earthquake.

In this challenge, each group will use same structure on the moving plate and will add steel balls $($following figure$)$ in the structure.

Page $1$ of $12$

Your designed structure will be placed on the top of this moving plate with the steel balls and will be operated such as the earthquake.

Score: When your structure stays on the plate more than $10sec,$ it will pass

There ase $5$ levels of the vibration of the plate.

$2$ pts for each level.

Total point $=($Points from level $x$ number of balls$).$

Design Constraints

The structure should be one Part file

Maximum dimension of the structure

Minimum Height $3$ in

Storage place height : Minimum $2.$ in from the bottom of structure

Your designs must mininize the overall weight and volume of the $3D$ printing material bed in the construction of this project

Must not use more than I in of material
