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

In summary, the conversation is about how to calculate the thickness needed for a circular plate with a big hole in the center to be able to support a 1 kg object placed on top of it. The plate is supported by 3 bars and the question is not for a specific solution but for a way to compute it for a chosen material. A picture of the plate is also provided. The book "Roark's Formulas for Stress and Strain Chapter 11" may have the answer to this question.

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.

1. How do you determine the needed thickness of a hollow metal disc for loading?

The needed thickness of a hollow metal disc for loading is determined by various factors such as the weight and size of the load, the material and strength of the disc, and the intended use of the disc. Engineers and materials scientists use mathematical equations and simulations to calculate the necessary thickness for a given application.

2. Is there a standard thickness for hollow metal discs used for loading?

There is no standard thickness for hollow metal discs used for loading as it depends on the specific requirements of the load and the application. However, there are industry guidelines and standards that recommend minimum thickness for different types of loads and materials.

3. How does the thickness of a hollow metal disc affect its load-bearing capacity?

The thickness of a hollow metal disc directly affects its load-bearing capacity. A thicker disc can bear more weight and distribute the load more evenly, making it stronger and more stable. Thinner discs may be more prone to bending or buckling under heavy loads, resulting in a decreased load-bearing capacity.

4. What factors can cause a hollow metal disc to fail under loading?

Several factors can cause a hollow metal disc to fail under loading, including inadequate thickness, excessive weight or force, poor material quality, and improper design or installation. It is crucial to consider all these factors and ensure that the disc is designed and manufactured to withstand the expected load.

5. How can you determine the appropriate thickness for a hollow metal disc for loading?

The appropriate thickness for a hollow metal disc for loading can be determined through calculations and simulations by qualified engineers and materials scientists. It is essential to consider the load, material properties, and intended use of the disc to determine the optimal thickness for maximum load-bearing capacity and safety.
