  • How Torque Is Measured? Cheater Wrench™

    Remember – torque is simply a measurement of the force acting on a rotating shaft. To find this, we multiply the force by the perpendicular distance of the force area. T = F * L; F= force (lbs) and L= perpendicular distance of the force area. When torque is measured correctly, we can save unnecessary wear and tear on machines and equipment.

    Over-torqued nuts and bolts can cause permanent damage to them. Too much force by the NASCAR mechanic can rip threaded fasteners off the wheel and cause the bolt itself to potentially crack and break. A calibrate torque wrench is recommended to ensure an accurate torque measurement and to

  • aircraft maintenance - What does "running torque" mean ...

    Jun 05, 2020  $\begingroup$ Yes running torque is the friction present while turning in the threads you have to allow for. You run it in to 80 inlb +/-, back it out half a turn, and as you start to re-tighten, measure the torque present as you start it moving through that half turn back toward tight, add 15-20 on top of THAT, and tighten to the 15-20 plus what you measured running.

  • Fastening Threads: Torque Audits Are a Good Way to Check ...
