90 degrees gives a true torque reading because it factors out the additional torque added by the mechanical advantage of the 12 square drive hole being a certain distance from the center line of the barrel nut in this case. Torque wrench adapter extended equations calculator.
How To Use A Torque Wrench
Torque wrench 90 degree extension. To calculate the true torque for the fastening application use this formula. Bulltools 12 inch drive click torque wrench set dual direction adjustable 90 tooth torque wrench with buckle10 160ftlb 10 210nm 43 out of 5 stars 47 6997 69. At 90 degrees this extension does not change the torque value. The following is the calculations one would use to determine the actual torque applied when using an extension or crow foot. Straight torque adapter with extension. When using extension adapters and spanners the torque applied to the fastener is greater than that preset torque setting or the torque value displayed on the tool.
The longer the extension or the thinner it is the lower the spring constant. I also believe that a relatively short extension at 90 degrees will keep the torques in the ballpark. Torque engineering and design menu. Straight torque adapter at 90 degrees. Acdelco 38 digital angle torque wrench 5 to 995 ft lbs buzzer vibration flash alarm iso 6789 standards with certificate of calibration arm315 3a 38 out of 5 stars 19 18598 185. Reversed straight torque adapter with extension.
15 degree wobble extension. A bar under torsion twist acts like a spring. The stored energy in the spring torsion ed bar is a large force applied in a short period of time and can be balanced by a smaller force at a longer period of time. Torque wrench extension calculator. 97 2257kg 10998 10998. Half moon wrench left.
Torque wrench with extension. It is adding quite a bit of distance to the torque wrench and therefore increases the torque applied by over 25. Calculations for torque wrench extension adapters and spanners. Here is that same extension but now it is in line with the torque wrench. Half moon wrench right. Crows foot at 90 degrees.
I would think a longer extension or any for that matter does bring the hypotenuse into play and is evidenced by your forearm no longer being 90 degrees to the torque wrench handle. To ensure that the proper torque is.
