mechanical calculations for custom made hinges
(OP)
dear's
kindly, i need your help for the calculation of the attached fig.
the door weight is 5 KG, the weight of each hinge 350 gram.
the size of the hinge is 100 mm from center to center
the distance in the box for the hinge is 40 mm from center to the edge
the fixed washer in the box height is 23 mm
the axles are M 10 SS bolts (10 mm)
all materials are in SS 316 grade
your quick response is highly appreciated
thanks on advance
Arafat

RE: mechanical calculations for custom made hinges
Knowing the weight of something is useless unless you know where the gravity vector is.
Which way is up?
I'll ignore the weight/mass confusion for now.
Boxes are usually full of something at some point in their lives.
What might it be full of?
Will the box ever be positioned so that the weight of the contents bears on the door?
What holds the door closed then?

all this SS makes me think there's something going on that we're not being told ...
what are those two "propeller" type things (that'll be inside the box when the lid's on) ?
does it get hot ?
the devil is in the details ...
how tight at the bolts in the holes ? (I hope it's a sloppy fit, 'cause there doesn't look to be much adjustment)
is there a bushing in the holes ? (so that the hinges are not being tightened up against each other)
how much moment do you expect at a hinge ?
do you seriously think that (multiple) 1/4" thk SS lug will have difficulties with 5.7kg ? (if that is the load) ... "PBI"

I am assuming that the "lid" is on the top, and his sideways view is rotated 90 degrees => Door/lid is on top, the two handles are to hold it closed (maybe by twisting under the complex folds just under the joint?).
No external handles or any way to lift the thing - gonna be heavy if filled with water, but 5,700 kg? That's more water than the box can hold.
Now, if the L-brackets are the hinges, then they need to be supported 2-3 inches away from the side somehow.
RE: mechanical calculations for custom made hinges
or are you using a "European" comma = decimal point ?
but then <6 kg of water isn't much volume ...
