b) the mass moment of inertia about z axis passing the rotation center O is:

c) The mass moment of inertia about z axis passing the rotation center O is:

Answer:
Explanation:
1.2(0) + 3(0.8) + 1.4(0.8/2) / (1.2 + 3 + 1.4) = 0.5285714... ≈ 0.53 m
These elements are synthetic elements in that they do not occur naturally and only as a result of being made in a scientific laboratory. Elements are given the Uu(x) name as a placeholder until IUPAC (International Union of Pure and Applied Chemistry) approves an actual name for the element. This is under a process called "systematic element naming" (feel free to give it a google). The IUPAC grants the discoverers of the new element the right to suggest the name for that new element, so you may find that those weird Uu(x) elements have an actual name soon!!
The 3rd class lever is the <span>output force always less than the input force, becuase its mechanical advantage is always less than 1. this also due that in a 3rd class lever the effort arm is shorter than the load arm, that is why the output is lower than the input force. but 3rd class lever is a speed multiplier lever</span>
Because it spin so slow over the course of a whole day.
