A bear managed to bend a steel door to a food locker in Yosemite. The door is hinged on one side and pinned on one corner ( the camper forgot to close it properly!!) , so the bend is across the diagonal. I wondered how much force the bear had to use to bend it. The doors are about 24" square and about .1" thick. Anyone have any ideas? My calculations based on sheet metal bending formula come out to nearly 7000 pounds., and I do not think a bear can have that much strength. I have a jpg of the bent door if anyone would like to see.
