Hi everyone, it's my first post!
I need to elevate a bed by 4 inches for a while. I did some work on this problem already. Here's all the information I used to reach my conclusion:
expected total weight with mattress and occupants = 220.92200 kilograms
bed weight = 54 kg = 54,000 grams = 119.05 lb
bed dimmensions = 199.4 x 106.7 x 149.9 cm
cross section of the legs = 6.205 cm
radias of the legs = 3.10125 cm
area of the legs = 30.22 cm2
circumference of leg = 19.5 cm (Does not reflect the actual around of metal contacting floor)
Bed image = https://www.amazon.com/dp/B0040V9ZWE/?tag=pfamazon01-20
My original plan was to get PVC and just put the PVC around the legs of the bed. I looked it up and PVC's compression strength and modulus are about =
Clear PVC pipe Physical properties
Compressive Strength psi @75°F 8,300
Compressive Modulus psi @ 75°F 307,000

PSI to Pa conversion
8,300 PSI * 6,894.76 Pa/PSI = 57,226,508 Pa
307,000 PSI * 6,894.76 Pa/PSI = 2,116,691,320 Pa
I ran the numbers assuming that I could use the pressure the legs exert as a decent yardstick to approximate how much stress the PVC would have to endure:
220.9220 kg * 9.8 m/s^2 = 2 165.0356 Newtons
2 165.0356 Newtons / 8.96 centimeters^2 = 2,416,334.38 pascals
Now the 8.96 cm^2 figure is based on the thickness of the beds legs which are hollow.
2,416,33.38 Pa < 57,226,508 Pa & 2,116,691,320 Pa
But... I feel like I'm missing something with this. I want to verify my conclusion before going ahead with this.
If my stuff is completely bogus then by all means suggest an alternate method.
