How to Calculate Torque Wrench Extension 

Thank you! This is a perfect, succinct explanation and description of the equations. And your last sentence are very true words.

Please note, that solutions provided for L1 and L2 @ 7:52 are switched. I made the mistake during transferring equations from my notes to the computer screen. I apologize for the mistake.

I did research and maths to come to this solution. Because it feels wrong. This would have saved me so much time. Such clarity!! Very eloquent!! Why I love the maths, Even when forgetting!! Thank you:::

Best advice is at the end!

Great demonstration.

Does this means when i extend more, higher torque are needed in order to get the same torque, for example in order to have the same 61nm with a 20cm extension, i will need to set my torque wrench to mayb 80/90 in order to get bolt tighten at 61nm?

very helpful!

Good tutorial. Thank you

Awsome! Awesome!! 👍👍

0:10 - if u r allergic to turds LoL

There is nothing to calculate. You can stick the crows foot straight off the end of the torque wrench. In statics engineering class we learned that the total torque on the crows foot must equal zero. Otherwise, it starts spinning in space. Whatever torque is applied by the wrench to the crows foot is felt at the bolt and the bolt must resist with an equal and opposite torque. No need to change the torque setting on the wrench.
