I had a rush job to straighten out a bent segment on a aluminum frame. The piece is 24" long and 2" X 3" and 1/8" aluminum, most likely 6061.
It had a 2" bow in it (the hard way), I tried a 4 ton porta power, no luck. Jumped up to a 25 ton cylinder still wouldn't budge.
Finally got out the old 20 lb. sledge, worked it back straight not pretty, but it worked..
This brings me to my question.
How much force does a sledge generate ? It was swung horizontal, and it was swung about 3 feet and it wasn't a full power swing.
How would you figure the force generated by the blow ?
Had to be way more than 50,000 lbs of force, because it moved reasonably easy ?
P.S. I am not a sledge kind of a person, this was a last resort.
