Swinging force and handle length
For instance, why does a sledgehammer have a handle about 4ft long? Why not 5 or 6ft? 6ft might be more unwieldy but wouldn't it technically produce more power? This goes the same for axes and such. They all seem to have about the same handle length, and I'm wondering how they came to that conclusion.
Is it force? Is it efficiency? Speed? More work done?
