# 2 Defining the bending point of the reaction bar, Fig. A

Use a piece of paper to make the drawing and measurements. Use a ruler and a protractor for accurate drawings.

- Determine the minimum angle a, according to the table.

- Determine the contact point (K) of the reaction bar. Make it as far away from the tool centre line as possible.

- Measure the resulting angle a, and make sure it is greater than the table entry for the selected torque.
