So, the longer the arm, the less force required...
I'm going to get laughed at for reviving such an old thread but I couldn't resist (made an account for it and everything)
you're right... to an extent. torque is measured at the fulcrum point, but when you add extension bars (socket side) you're also reducing the torque you're applying, a lot of the energy being applied gets stored in the extensions and therefore you're not getting the torque you're quoting.
proper torquing is achieved with a torque wrench and no extensions... once you start adding cheater bars or extensions you might as well just use a normal ratchet/breaker-bar.
