WebPoint-masses mi are located on the x -axis as shown. Find the moment M of the system about the origin and the center of mass x. Transcribed Image Text: Pont e loted n t e the … WebIn the case with the axis at the end of the barbell—passing through one of the masses—the moment of inertia is {I}_ {2}=m { (0)}^ {2}+m { (2R)}^ {2}=4m {R}^ {2}. From this result, we can conclude that it is twice as hard to rotate the barbell about the end than about its center.
Webthe moment about the yaxis is given by M y= m 1x 1 + m 2x 2 + + m nx n and the moment about the xaxis is given by M x= m 1y 1 + m 2y 2 + + m ny n: These moments measure the tendency of the system to rotate about the xand yaxes respectively. The Center of Mass of the system is given by ( x; y) where x = M y m and y= M x m for m= m 1 + m 2 + + m n: WebThus, M = −E H. Use the result of part (a), we get M = Nµtanh µH kBT. 3.3 Spin Systems in aMagnetic Field Reif §3.3: Consider two spin systems A and A′ placed in an ecternal field H. System A consists of N weakly interacting localized particles of spin 1 2 and mag-netic moment µ. Similarly, system A′ consists of N′ weakly ...
