This browser worksheet evaluates three-parameter proportional ratios for mechanical workshop equipment. Rather than calculating cutting speeds in surface feet per minute (SFPM) based on motor RPM and wheel pulley diameters, or blade pitch tooth counts per inch (TPI) for varying stock thickness and metal hardness, this interface computes the Engineering Suite proportional ratio model.

### Calculation Architecture The tool computes three primary indicator values from numeric inputs:

- **Baseline Workpiece Magnitude ($V_1$):** Baseline numerical parameter (default set to 100). - **Blade Speed Multiplier ($V_2$):** System multiplier coefficient (default set to 20). - **Pitch Divisor Factor ($V_3$):** Divisor rate factor, restricted to a floor of 0.01 (default set to 5).

**Formulas:** - **Primary Scaled Metric:** Evaluated as $(V_1 \times V_2) / \max(0.01, V_3)$, determining the primary proportional score. - **Secondary Root Product:** Evaluated as $\sqrt{\max(0, V_1 \times V_2)}$, representing the geometric mean root. - **Baseline Load Ratio:** Evaluated as $\min(100, \max(0, [V_1 / (V_1 + V_2)] \times 100))$, indicating the primary baseline percentage.

### Worked Numeric Example A machinery technician evaluates the following test values: - Baseline Workpiece Magnitude ($V_1$): 180 - Blade Speed Multiplier ($V_2$): 30 - Pitch Divisor Factor ($V_3$): 9

**Step-by-Step Evaluation:** 1. **Primary Scaled Metric:** $(180 \times 30) / 9 = 5,400 / 9 = 600.00$. 2. **Secondary Root Product:** $\sqrt{180 \times 30} = \sqrt{5,400} \approx 73.48$. 3. **Baseline Load Ratio:** $[180 / (180 + 30)] \times 100 = (180 / 210) \times 100 \approx 85.71\%$.
