Bought this thinking I wouldn't need it only to end up using it to take off a super tight hub nut on my car about 2 weeks later. The bar bends quite a way and I was happy when leaning on it, feet off the ground, a 100kg me was able to _just_ get the nut moving. Torque must then have been..
F=mg=100×9.81=981 N
24"=2 ft=0.6096 m
τ=F×r=981×0.6096=598 Nm (approx.)
Nearly 600Nm (443 lb ft) and it didn't cave?? That's over double the manufacturer's torque spec for the ut at 270Nm. Why mechanics do this is beyond me.
Summary: Pretty solid. You can take this breaker bar to the bank.
