GD2 is defined as a mass moment of inertia with respect to its axis. Some how their is some misconception that GD2 is two different variable, however it is not. Likewise, I=mk2, we have to calculate the mk2 about its central axis.
Formula: Gd2(C2O4)3
Mass moment of Inertia of the motor/Gearmotor is called GD2
I have had a lot of experience with image modification modules with PHP. In order to perform image manipulation in PHP you need an image processing module installed such as GD2 or imagemagik. GD2 comes with PHP and can be installed fairly easily if it is not already installed. You can follow the PHP GD manually for the usage of these functions.
The gd2 value for a motor represents the motor's rotational inertia, which is a measure of how difficult it is to accelerate or decelerate the motor's rotor. It is calculated by multiplying the motor's moment of inertia (I) by the square of the gear ratio (g). A higher gd2 value indicates a greater resistance to changes in speed, which can affect the motor's performance and efficiency in applications requiring frequent acceleration and deceleration.
There has been a change in the shape of earth crust due to this terrible earthquake caused by displacement over Asian tectonic plates. This has resulted in 8 feet around/ over the epicentre. Such a huge change in shape of earth's crust, resulting change in earth's momentum/ GD2 around Sun; resulting our day is now shorter by fraction of micro-second!
