I can understand that this formula wants to consider the nonlinear state of stress distribution especially when the pressure is high and hence the thickness is high. However, what I do not understand is the origin of that factor 0.6 by which P is multiplied.

If shelf span is increased … WebMeasuring thickness requires a tool with great precision such as calipers. However, if you know the area, mass, and density of a substance, then you could calculate the thickness. Use this formula to calculate thickness: thickness = volume area. To find the volume, you would rearrange the density formula. volume = mass density. screenshot for your reference

What are cheap ways to build strong shelves with a large span?

WebSep 14, 2024 · The corresponding thickness distribution and the vertically integrated flow can be inferred from Figure 3. All contributions of ice across the boundary from a virtual catchment area and from precipitation are balanced by calving into the ocean. Ice thickness varies from >1000m at the inland boundary to <200m at the ice-shelf front. WebSome of the shelves I would like to span quite a width. For example, 2 meters, and be quite deep (say 50cm). For aesthetic reasons I would like them to be supported only at the back and each end, avoiding large brackets or similar underneath the shelves as far as possible. One way to do it would be to buy very thick strong material for the shelves.
