Lab Report ExampleOn the shortest axis, the dynamic snatch of inertia was more than the unruffled inertia. This also applies to the yenest axis where the dynamic moment is far more large than the tranquil.The difference spy from the determined dynamic and static moment of inertias is an illustration that the rotational axis has a core enjoyment in rotational motion. In normal case, especially where there are no deformations, the dynamic moment of inertia and static moment of inertia are equal, except for small errors that may result from data-based undertakings. The difference exhibited between the two moments of inertia can be attributed to the change in the rotational axis. As the axis is moved from the shortest hole to the longest hole, the deformation (change) contributes to the change in the resistance of the object to angular acceleration. Just like in linear motion where, when the object is rotated about a long axis, the acceleration is likely to reduce as compared to w hen subjected to a shorter axis.Further, the clangor was also determined to be a contributing factor to the difference between static and dynamic moment of inertia. Intuitively, dynamic cases are supersensitized to friction effect because of the movement exhibited, unlike in static where an object is fixed. As shown by the higher(prenominal) value of dynamic moment of inertia than static moment of inertia, friction had a stake in this. In which case, friction resulted to a too high value for Id during the experiment. Friction force acts in slow down the rotational acceleration consequently enforcing the ability of the object to resist the angular acceleration. Consequently, addition of friction adds to the resistance of the object to friction, which in turn increases the total dynamic moment of inertia. In the case of static moment of inertia, there is no friction exhibited consequently the resistance (moment of inertia) is not in any modal value affected.The results show that th e rotational kinetic
