I'm using the basic deflection equation to determine how thick a plate of steel would have to be to support a load of approximately 1300 N in a 3 point bend, with surface dimensions of of 420 x 630 mm.
I = bh3/12; δ = FL3/(C1EI); Esteel = 200 GPa = 200 N/mm; δ = 50 mm (arbitrary);
h3 = 1300*(4203)*12/(48*50*630*200)
I'm getting a result of 15 mm... to me that seems a bit thick, especially when the weight would be close to 33 kg. Am I missing anything?
Thanks
