Need an engineer to calculate stress loads

[Okiehunter]

Is there an engineer out there that can calculate stress loads for me?

I am building feeder “platforms” out of 2” 1/8” angle. The platforms are ~23.5” square. On all four corners I am welding and bracing a 10” schedule 40 round black pipe 1.25” leg bracket. I am setting the leg brackets at 22.5 degrees. I am currently using 1” schedule 40 round black pipe that is just over 5” long as legs (the legs slide into the 1.25” leg brackets.

My question is, is there a lighter weight steel I can use for the legs to support 500+/- pounds of feed in the barrel?

Thanks

The answer is complicated and you don't have enough information. Technically, a 1/2" x 1/8" aluminum angle will hold 500lbs in vertical compression.
However, I understand your question. You need it to be able to take the weight, wind, rocks, deer/hogs, moving, etc. You want it to be as cheap, light, and readily available materials as possible. (many calculations, CFD, FEA, and other acronyms to determine the perfect scenario). I don't need to perform calculations to tell you that you are as light as you can be right now without going causing problems, or going to exotic materials.
I know I didn't answer you question directly, but hope it helps.

Beware of asking for an engineer. You're probably thinking an engineer will perform detailed calculations and give you an answer backed by known materials science and design principles. What you'll actually get though is a scientifically influenced WAG that the engineer is confident nobody will be able or willing to spend the energy to prove him or her wrong.

With that said, as an engineer myself, I would say since you have 4 supports sharing the 500lbs, you can definitely use lighter pipe. [emoji106]

I agree that you could go with something lighter. The longer the legs, the more apt they are to bend and stress. Might consider staying with heavier legs if you have livestock or hogs.

I have used 7 foot long legs on a 600# corn feeder...three legs of 1 inch sched 40 pipe.

BTW, I am not an engineer but I have designed and built some stuff

I'm not an engineer BUT I can tell you 5 inch long legs WILL NOT WORK! your timer is going to be touching the ground!

there is a reason I am no engineer, to dang many details. Make that 5 FEET legs.

While they're at it, can they tell me if a 6' trailer is enough for my wife?

Best thread title of the year!

NOT at all. This site and many others like it provide help to one another. I spent about half an hour today PMing back and forth helping a fellow TBHer with an arrow question. I have been on this forum since before the crash and have spend no telling how many hours offering help where I have expertise and even given money to TBHers that I don't know nor will ever meet when they were in need.

I am guessing you just don't get it. Some folks call it "pay it forward". It is you and others like you with that attitude that keeps me (and others) off this and other forums. I have seen a lot of it on here and it is too bad for TBH, too bad for many wanting and or needing help with something and mostly too bad for you cause you are the real loser to the benefits of being a member of this group.

I can do the stress analysis but there is no need. I can tell you from personal experience that 2" emt conduit will hold the feeder weight plus a 300lb guy on one of the legs.

Good words here. If you get an engineer they will tell you it loads eccentrically in the wind so you will need a concrete slab 12' X 12' and 18" thick to keep it from overturning. [emoji857]

For real I would not go smaller or lighter than you already have it. Better put a base on those one inch legs or they will sink when it rains like they are in quicksand.


I started with nothing and still have half of it left.

Dude chill out! Go drink a beer and come back with a better attitude.
