Image:Free body diagram mod.png‎

Hi Theo. Just to let you know that I reverted the changes you made in good faith to Image:Free body diagram mod.png‎. Although what you changed it to is a common schematic in school mechanics, it is an ambiguous way of drawing a free-body diagram. It assumes the block to be a particle not a 3D free body, despite depicting the shape and size of the block. The original renders the forces originating from the centroid of their action. It's not perfect, but less likely to mislead. BigBlueFish (talk) 15:54, 9 June 2008 (UTC)[reply]

That's a good point. I was trying to keep it consistent with similar diagrams on wikipedia, such as the inclined plane page. However, given inclined plane problems are treated as if one is dealing with a point particle, drawing as I'd done made sense. Whereas, as you rightly point out, the coefficient of friction version of an inclined plane should draw the forces originating from good approximations of where they act. If only I'd thought of that myself... It might be worth making that point on the coefficient of friction page itself, or on the talk page? This is why I changed it as people were discussing this exact point. I'm happy for you to add this exchange to that page (or I can with your approval?). Clark (talk) 14:40, 6 July 2008 (UTC)[reply]
