thread507-1083: load capabilities of steel fletch plates c16 and c24 sw timbers will take stress of 5.3n/mm2 and 7.5n/mm2 respectively.What would this be increased to ,by the addition of a 12mm ms plate sandwiched between two members.

The various members (steel or wood) share the load on the beam in proportion to their relative stiffnesses, both moment of inertia and modulus of elasticity. Once they are joined together, they will all deflect the same (as one beam) under the load and the trick is to connect them together so as to cause the required force transfer between them and at the same time not overstress any of them. As mentioned above by DST148 any number of Strength of Materials or Structural Engineering texts will lay this design process out in more detail. The most complicated part of the design is this force transfer interconnection of the members, and the shear and end bearing details.
