For the Mathematicians:
I have a torque wrench that will only measure as high as 150 ft-lb. I need to torque a couple bolts to 300 ft-lb. I don't want to buy another torque wrench that will measure that high because I don't ...

First of all I think the assumptions made here are not quite correct.
IF you have a torque wrench that will read 150# at it's Maximum using a breaker bar of any length ONLY DECREASES the effort to reach the 150. It does not double the effective Torque. This assumes you stop the needle on the 150 mark or it clicks whichever type you have.
You need a Multiplier socket as mentioned or a 300Lb/ft Wrench.
Now without a Torque wrench and with a normal 3/4 drive socket and breaker bar you will be able to reach 300# but you wont know when you've reached it.
Using a breaker bar with a torque wrench will not double the capacity of the Wrench it only Decreases your effort to achieve that capacity.
Yes, I misspoke earlier, but the link I provided was good...after I posted, I figured someone would catch it...you have to extend the right section to make it work...

Yes, as I said, I misspoke....if you extend the distance between the bolt and the measuring device, the resultant torque will be greater than the applied torque. With an Aero Undergrad degree and a Masters in Systems Engineering, I hardly think I was just educated, but thanks for the civility and happy holidays.
