Hollow Metal disc loading - the needed thickness of the disc?

  1. Dec 11, 2011 #1
    Hi,
    how to calculate the limit of load you can place on the top of the circular plate with a quite big circular hole in it (OD 10 cm, ID 5 cm)? the question is how to calculate the thickness needed to bear 1 kg which is spread on the whole area (1 kg heavy object with the same shape as the plate, a hollow cylinder 10 cm x 5 cm x some height). The plate is in the air, supported by 3 bars on the ring of the plate.
    thank you for any help/advice! This is not a homework, I don't want to "get the solution" but be able to compute it for material I'd use than.

    Roark's Formulas for Stress and Strain Chapter 11 has this.
