Before we can consider the rotation of anything other than a point mass like the one in Figure 2, we must extend the idea of rotational inertia to all types of objects. To expand our concept of rotational inertia, we define themoment of inertiaIof an object to be the sum ofmr2for al...

For example, a continuously oscillating cylinder can generate steady streaming and capture surrounding cells near the cylinder. As shown in Fig. 7(a), Fuchiwaki et al. [154] used a micropipette as an oscillating cylinder. In this case, once a cell is trapped by the eddy flow near the ...
What is the magnitude of angular momentum of the cylinder about its axis ? View Solution A wheel having moment of inertia 2 kg m2 about its vertical axis, rotates at the rate of 60 rpm about this axis. The torque which can stop the wheel's rotation in one minute would be View ...
Typically, the properties of an object's motion change depending on how it is rotated. Consider a cylinder, half of which is made of lead and the other half of which is hollow. If an axis of rotation were chosen through its long axis, the distribution of mass around this axis ...
1.The rotational inertias about generator of common uniform revolutional rigid bodies(circular cone and frustum of cone)are simply calculated by using the method of rotational inertia tensor and the parallel axis theorem,and the rotational inertia of cylinder is given as a special example.运用惯量张...

The rotational moment of inertia of a body has a radius of gyration Rg, which is measured relative to the body center of mass. One must integrate over the volume, which contains the solute particle. The above expression of Eq. (214) can be factored, which isolates the radius of gyration...
