# Beam Analysis Calculator with Natural Language Explanations

This Space implements a deterministic engineering calculator for a simply-supported beam with a central point load.  
It shows (i) numerical results and (ii) a natural-language explanation grounded in the computed values.

## Scope and assumptions
- Simply-supported beam, central point load
- Square cross-section, linear elastic material
- Strength check against yield; serviceability check against L/360 deflection

## Inputs and ranges
- Beam length L: 0.5–10.0 m
- Square side a: 0.01–0.5 m
- Load P: 0.1–100 kN
- Elastic modulus E: 50–300 GPa
- Yield strength Sy: 100–1000 MPa

## Outputs
- Max stress, max deflection, allowable deflection
- Factors of safety (yield, deflection)
- Pass/fail checks and overall verdict

## Explanation pipeline
A compact language model (SmolLM2-135M-Instruct) consumes the structured record from the calculator and produces a concise explanation.  
The prompt enforces grounding and avoids introducing numbers beyond what was computed.
