Ok, lets say I have (2) strips of sheet metal, 0.125in thick 5052AL, x 0.63in wide, 10 inches long. (shush you metric folk, its just a fad and you know it) Sandwiched between is a piece of rubber, size and shape arnt important, for the discussion, it is simply applying a load in the middle of the 10 inch span. The sandwich is clamped together at each end. If the total resistance of the load of the rubber is 10 lbs, am I correct that only 5lbs is acting on each piece of sheetmetal? Neither side of the sandwich is supported on its length.
Thanks!

according to the basic force calculations the total weight is distributing itself trought the construction to the ground or etc.

so, when you start calculating from the lowest plate, there is 10 lbs on the lowest AND 10lbs on the upperest plate.

when you calculate out of the gravity center of the rubber piece (what is very unusual) there is 5lbs on each side of the rubber piece.

tip: start your calculation always from a fitted (not variable) point and search then your bending amount and shape changes due to the forces
