| Well as far as I'm aware, that is the most commonly used symbol for the damping ratio.
And I appreciate the limitations due to the font, and as such, I have tried to remove any ambiguity by not using multiple symbols which may be mistaken for one another. Yes it's a little difficult to distinguish between the alpha and a lower case 'a', and that's why I've not included any variables that are usually represented by a lower case 'a'.
Even if you can't tell whether it's an alpha or a lower case 'a', you can deduce that it must be an alpha by looking at the possible answers. |
