Answer to Question #22845 in Mechanics | Relativity for Lee

Question

I am trying to calculate the center of mass on a project I am building but I'm kind of lost on how to figure it out. The overall length is 159.5" and width is 52", starting weight is 90lbs with a weight of 175lbs 54" centered from the left end, before the cross bar and 80lbs 82.5" centered from left end. With an overall weight of 345 lbs. It is built in a t shape.
