Thank you for your answer. Yes, in option A, force that moves the table creates a moment that wants to spin the table arround the X axis (creates forces at the Y end points of the table, that push one endpoint up, and the other down). And there's also bigger strain at the point where support is connected to the table. But table rests on the blocks/rails that ensure rigidity and will dissalow bending. I'm interested in how will these options handle table intertia, and why.
