This interactive calculation utility evaluates three-variable engineering parameters for fabrication and welding process estimates. By adjusting your primary load, operating coefficient, and secondary rate, the calculator derives the primary ratio metric, the geometric operating coefficient, and the relative load percentage.

All formulas evaluate immediately in your browser tab without submitting figures across the network.

### Mathematical Formulas Evaluated 1. **Primary Ratio Metric**: $$ ext{Primary Metric} = rac{ ext{Primary Load} imes ext{Operating Coefficient}}{max(0.01, ext{Secondary Factor})}$$ 2. **Operating Metric**: $$ ext{Operating Metric} = sqrt{max(0, ext{Primary Load} imes ext{Operating Coefficient})}$$ 3. **Ratio Efficiency Percentage**: $$ ext{Efficiency (%)} = left( rac{ ext{Primary Load}}{ ext{Primary Load} + ext{Operating Coefficient}} ight) imes 100$$

### A Worked Numeric Example Using default inputs: - Primary Dimension / Load ($v_1$): 100 - Operating Coefficient ($v_2$): 20 - Secondary Factor / Rate ($v_3$): 5

Calculations: - Primary Metric: $(100 imes 20) / 5 = 2000 / 5 = 400.00$ - Operating Metric: $sqrt{100 imes 20} = sqrt{2000} approx 44.72$ - Efficiency: $[100 / (100 + 20)] imes 100 = (100 / 120) imes 100 approx 83.33%$
