Wrench Resultant

When a resulting couple of vector is M and R, is the resultant and both are parallel to each other, then it is called a wrench.

Fig. 3.16(a) Positive wrench                        Fig. 3.16(b) Negative wrench

Now the original vectors M and R are replaced by M1 and R, and they act at a single point which is positioned far from the original points. This is made easy by the diagrams given below:

We can consider screwdriver as its best example.
