Center of mass rotation
WebIn an experiment, a solid, uniform disk of mass 0.2kg and radius 0.5m is suspended vertically and can rotate about its center axle such that frictional forces are considered to be negligible. A string is wrapped around the pulley with one end connected to a block of mass 0.1kg that hangs from the string at rest, as shown in Figure 1. WebNov 5, 2010 · There you have the center of rotation. Update: If you don't have the correspondence of which point went where, it shouldn't be too hard to figure out. Here is a suggestion from top of my head: Find the center of mass of the "before"-points. Order the points according to their distance from this point. Now do the same with the "after"-points.

WebThe Center of Mass Interactive allows a learner to explore the effect of object shape upon the center of mass. Draw out a shape on the workspace and watch the center of mass change its location as you change the shape. Then pin the shape on the corkboard and see how it hangs. Can you find the pattern between the pivot point from which is hung ...
