It is convenient to perform two separate integrations for the areas A and B. First we compute the 'whole mass'...
(1)
... and then we compute and ...
(2)
(3)
The results are shown in the figure...
Kind regards
The object above has a uniform cross-section. It is made of two materials that have different densities. Part A's density is and for part B Find the coordinates (x,y) of the center of mass for this object. You may consider a part of the object that is one meter long in the z direction.
I don't even know where to begin, the workbook I have does not seem to have any similar examples nor my lecture notes.
