Horizontal or vertical strips when solving c.o.m. of functions problems?

Nikitin · Oct 12, 2012

Is there any decent way to quickly spot if I should divide a 2d figure defined by functions into horizontal or vertical strips when solving centre of mass problems? Or does it come down to experience and/or math-talent?

Problems like the1 in this video is what I'm on about: http://www.youtube.com/watch?v=1dsOuz05pSE&list=LL4e6ou1LiIi_GQYUwVwal1A&feature=mh_lolz

Shouldn't this be in the math section? A moderator moved it from there and to here, but that was before I updated my OP with a youtube video explaining what I'm on about.

Can some moderator move it back, or at least answer me?
