Truss moment of inertia

WebThe included angle between every two energy-storage-type variable-speed control moment gyroscopes ranges from 0 to 180 degrees. The invention also discloses the vibration energy integrated control method for a flexible spacecraft. The vibration energy integrated control method is used for controlling the moment gyroscope mechanism. Webmoment of inertia is the same about all of them. In its inertial properties, the body behaves like a circular cylinder. The tensor of inertia will take different forms when expressed in different axes. When the axes are such that the tensor of inertia is diagonal, then these axes are called the principal axes of inertia.
