The block is designed to simulate the rotary motion of a body having a variable moment of inertia. The block calculates the angular acceleration of the body and, using integration, determines the angular speed and the turn angle of the body. The angular acceleration
ε, rad/s
2, is calculated by the formula:
where:
- N – number of blocks connected to this block
- Ti – torque coming from the i-th block, Nm
- J – defined moment of inertia of the body, kg·m2
- Jmin – minimum moment of inertia of the body, kg·m2
