Eccentric Turning Calculator

Calculate Eccentric Turning Packing



Formula

The formula to calculate the eccentric turning packing (ETP) is:

\[ ETP = 1.5 \cdot OS \cdot \left(1 - \left(0.125 \cdot \frac{OS}{D}\right)\right) \]

Where:

Definitions

Example

Let's say the offset (OS) is 2 inches and the bar diameter (D) is 8 inches. Using the formula:

\[ ETP = 1.5 \cdot 2 \cdot \left(1 - \left(0.125 \cdot \frac{2}{8}\right)\right) \]

We get:

\[ ETP = 1.5 \cdot 2 \cdot \left(1 - 0.03125\right) \]

\[ ETP \approx 2.91 \, \text{inches} \]

So, the eccentric turning packing is approximately 2.91 inches.

How to Calculate Eccentricity

Definition: Eccentricity measures the deviation of a curve or orbit from being circular.

Formula: \( e = \frac{c}{a} \)

Example: \( e = \frac{3}{5} \)

Calculate the Eccentricity for a Circle

Definition: The eccentricity of a circle is always zero because the distance from the center to any point on the circle is constant.

Formula: \( e = 0 \)

Example: \( e = 0 \)

Eccentricity of Orbit Calculator

Definition: This calculator determines the eccentricity of an orbit based on its semi-major and semi-minor axes.

Formula: \( e = \sqrt{1 - \frac{b^2}{a^2}} \)

Example: \( e = \sqrt{1 - \frac{4^2}{5^2}} \)
