If we are rotating about the end of the rod, then the r’s can be set up such that Our integral then becomes and is solved At first glance, this doesn’t seem to contain the term MR² we predicted earlier, but it is, in fact, hidden inside the expression. We can find the MR² if we replace the linear density with the … Meer weergeven The case of the thin rod is slightly complicated by the fact that r changes as we move from place to place along the rod. We need to vary r from one end of the stick to the other. The integral is over dm, though, not r. … Meer weergeven Now we place this into the moment of inertia definition. We should pause for a moment to carefully choose our limits of integration. … Meer weergeven In this case, we carefully check our limits of integration.

The value should be lower because the mass increases as it approaches 1.9. So when you rotate it from the right side, it should be a lot easier to rotate the object and thus, a lesser value moment of inertia. Mar 15, 2009.
WebMoment of Inertia. We defined the moment of inertia I of an object to be [latex]I=\sum _{i}{m}_{i}{r}_{i}^{2}[/latex] for all the point masses that make up the object. Because r is the distance to the axis of rotation from each piece of mass that makes up the object, the moment of inertia for any object depends on the chosen axis. To see this, let’s take a …
