sampe		 Metal disc loading - the needed thickness of the disc? View All
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.
i need to say it for aluminium, I guess, another material is only constant change.

thank you for any help/advice! I don't want to "get the solution" but be able to compute it.

 Look at Roark's Formulas For Stress and Strain (1). All the equations you would ever need on the subject are there.
