Calculating Shuttle Loom Sley Eccentricity
This solution determines the sley eccentricity for a shuttle loom based on the provided crank radius and connecting rod length.
Given Data
- Crank radius ($r$) = 10 cm
- Connecting rod length ($L$) = 40 cm
Eccentricity Calculation
Sley eccentricity ($E$) is calculated as the ratio of the crank radius to the connecting rod length.
The formula used is:
$E = \frac{r}{L}$
Substituting the given values:
$E = \frac{10 \text{ cm}}{40 \text{ cm}}$
$E = 0.25$
Conclusion
The sley eccentricity is calculated to be 0.25.
