I have a question about translational equilibrium.(adsbygoogle = window.adsbygoogle || []).push({});

Consider a 3m by 3m sheet on the x-y plane. The center of mass is at the origin.

Force-1 of 10 N acts on the top left corner of the sheet and points left.

Force-2 of 20 N acts on the bottom right corner of the sheet and is directed downwards.

Force-3 of yet to be determined magnitude and direction, acts on the center of mass. I need to find the magnitude and direction of this force that will result in the sheet being in translational equillibrium.

I can do this problem if Force-1 and Force-2 acted on the center of mass, but in this case the first 2 forces act on corners of the sheet.

Does it matter that the first 2 forces are not acting on the center of mass? Is the problem equivalent if I promote the first 2 forces to act on the center-of-mass?

Thanks
