WebIntroduction. When a body is rotating, or free to rotate, around an axis, a torque must be applied to change its angular momentum.The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body.Moment of inertia may be expressed in units of kilogram metre … 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.
