When tightening the bolt with a wrench, can the tail of the wrench be lengthened?
Yes, but pay attention. Forcing will cause the screws to reverse or damage the spanner
The principle is not a wrench lever principle, because the spanner is rigid tool, it in the bolt on the torque locked, the torque is equal to the force multiplied by the arm, can increase the length of the same size to force greater torque wrench in the back, but the wrench length is calculated according to the yield strength, it the bending strength, if the increased strength of potential blindly, will substantially increase the tightening torque, can easily destroy the threads of the wrench opening also easy to cause damage.
Yes, but pay attention. Forcing will cause the screws to reverse or damage the spanner.
