optimum torque/tension figure for each fastening application. It is important to have these figures available so that the end product will be safe, efficient and economical. Diagram A
HOW DO WE MEASURE TORQUE? (Diagram B) Torque is the result of multiplying the value of Force applied by the Distance from the point of application.
Comparing the two examples, please note that the same Torque result can be achieved with a lower Force if the Distance from the nut/bolt is increased.
Diagram B
Torque = force x lever length of wrench: Force of 20 lbs. x 1 ft. = 20 lbf.ft or Force of 10 lbs. x 2 ft. = 20 lbf.ft
Another factor that affects applied torque when using torque wrenches is if it is “length dependent,” which means that the actual torque applied to the fastener varies if the hand position on the wrench is varied (even if the wrench is preset). This occurs if the pivot point of the wrench mechanism is not coincidental with the point of application of torque.
