# Ολυμπιάδα Επιστημών SkyCiv 2023 Εφαρμογή ανταγωνισμού

## Design and test your Tower structures, χρησιμοποιώντας την εφαρμογή Science Olympiad

Το SkyCiv συνεργάστηκε με το Science Olympiad για να βοηθήσει στην ψηφιοποίηση του διαγωνισμού Science Olympiad για το 2023-24 εποχή! The app sits inside SkyCiv Structural 3D to simulate the competition testing.

The SkyCiv Science Olympiad App will auto-analyze and test your structure based on the competition criteria. Instead of physically building the model and testing it under a load of a bucket of sand, the App will apply the load gradually and test it based on Finite Element Analysis. Key results are then displayed, with some insight into why the structure is failing. The app will also test the rules and guidelines of the competition, including the load distance, structure width, material usage, κι αλλα (Δες παρακάτω).

## Ξεκινώντας

After signing up for a Science Olympiad Account (or SkyCiv Student Account), login and visit your account settings: https://platform.skyciv.com/account/settings Under Add-ons and Integrations, you should see a Επιστημονική Ολυμπιάδα εφαρμογή. Switch that on and click Save Settings. Μόλις γίνει αυτό, επίσκεψη SkyCiv Structural 3D and you should see the Science Olympiad app under Add-ons στην επάνω γραμμή πλοήγησης:

Clicking this will launch the App and allow you to start testing your model.

## Building Requirements

Each individual event, ανταγωνισμός, or division may have its own set of building requirements. Ωστόσο, there are some consistent building requirements for the app, that should be met regardless of what level of competition you’re in.

### Φόρτωση περιοχής

• The number of Area Loads the Tower must support is two for Regionals, three for State, and four for Nationals.
• One Area Load must have nodes at (x = ±2.5 cm, y = 50 εκ, z = ±2.5 cm) for Division B and (x =±2.5 cm, y = 60.0 εκ, z = ± 2.5 εκ) for Division C.
• The other Area Load(μικρό) will have nodes at coordinates specified by the Event Supervisor in the range (-20 cm ≤ x ≤ 20 εκ, 12.5 ≤ y ≤ 37.5 εκ, z = ±2.5 cm) for Division B and (-20 cm ≤ x ≤ 20 εκ, 15.0 ≤ y ≤ 45.0 εκ, z = ±2.5 cm) for Division C.
• The y-coordinates for all nodes in an Area Load must be the same.
• Your area load should be a Τα φορτία κατανέμονται χρησιμοποιώντας μονόδρομη δράση -60 δύναμη kPa πάνω από ένα τετράγωνο 5x5cm. Κόμβοι φόρτωσης περιοχής (έτσι η διαδρομή φορτίου θα ταξιδεύει μόνο σε οποιοδήποτε από τα στηρίγματα ή εισαγωγή) θα πρέπει να εισαχθεί δεξιόστροφα ή αριστερόστροφα. Ακολουθεί ένα παράδειγμα σωστού εφαρμοζόμενου φορτίου περιοχής:

Επίσης, note the variance is 0.00% this is also required for the successful solve of your structure.

### Κατεύθυνση κτιρίου

You will also need to build your structure in the Y-direction. Πάλι, here is an example of a correctly built structure:

## Σημείο φόρτωσης

Each of the four nodes of the Area Load, must have a Point Load in the positive-z direction with magnitude 5–25 N, the same magnitude for all Point Loads.

## Υποστηρίζει

The Tower must be supported using exactly four supports placed in the plane of the Test Base (y = 0); two must be “Horizontal Rollers in X” with x-coordinates ≥ 20 cm and two must be “3D Pin Supports” with x-coordinates ≤ -20 εκ, without restrictions on z-coordinates.

## Ενότητες

The cross-section of individual members must be rectangular with minimum cross-sectional dimensions as specified in SkyCiv of 1.5 mm by 1.5

## Results and Scoring

### Main Results

The app will run through about 100 iterations to calculate the load at which the structure fails (if in fact, it fails). Κατά τη διάρκεια αυτής της διαδικασίας, it will calculate the following results:

• Max Stress: this is the stress that your members are undergoing under the peak load. If your structure is failing due to stress (stress exceeding 7MPa) then this result will hover under that stress limit.
• Βάρος δομής: the weight of the structure. This value is used as the denominator in the calculation of the performance score. So the lower this value, the higher your score.
• Χωρητικότητα δομής: how much weight your structure held (excludes self-weight).
• Βαθμολογία απόδοσης:
• Towers that have a Load Supported of 15,000 g will earn a Bonus of 5,000
• Score = Load Score (σολ)/Mass of Tower (σολ).

### Criteria Checks

In the background, the app will be checking the following:

• Materials used were one of 3 allowable Balsa Wood grades
• Plus more

These results will be submitted with your overall score to ensure the rules and guidelines of the competition are met.

### Λειτουργία ανταγωνισμού

On your designated event day, users will toggle on the Λειτουργία ανταγωνισμού στην επάνω δεξιά γωνία. Σπουδαίος: Toggling on this switch will delete your model, remove some of the functionality in S3D and limit the number of solves for 48 ώρες. Please do not toggle this on unless it is your competition/event day. The blue Submit Score button will also become available where you can submit your final score via the below form.
