Rotary moment of inertia#

The Rotary moment of inertia block model implements the solution of the equation of a rotating body motion with constant inertia (1):

(1)#\[ J\cdot\frac{∆\omega\left(t\right)}{∆t}=T\left(t\right) \]

where:

$J$ - Rotary moment of inertia, [kg$\cdot$ m$^2$];

$\omega\left(t\right)$ - angle rate, [rad/s];

$T\left(t\right)$ - resulting gyral (rotation) torque, [N∙m];

$t$ - interval, [s].
