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/Twin-Over-Bu...280771&sr=8-1-fkmr1&keywords=2256w+coaster+co 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 http://plascowelding.com/pdf2007/PV...Pipe&Fittings/PVC(SCH.40&SCH.80)ClearPipe.PDF 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.
