Final answer:
To take out bends when an angle is over bent, an external force can be applied to straighten the angle. Using a pipe over the handle of a wrench can increase the torque applied to a tight bolt and help remove the bend. However, caution should be taken to avoid excessive force that can break the bolt.
Step-by-step explanation:
When an angle is over bent, bends can be taken out by applying an external force to straighten the angle.
For example, if a connector is bent beyond a certain angle, a force can be applied in the opposite direction to straighten it. This force will reduce the angle and remove the over bending.
Let's take the example of a pipe placed over the handle of a wrench to remove a very tight bolt.
By extending the handle of the wrench with a pipe, the mechanic can apply a longer lever arm and increase the torque applied to the bolt.
This extra torque helps in loosening the bolt and taking out the bend caused by excessive tightening.
It's important to note that while using a pipe can help in removing a tight bolt, it can also be hazardous if too much force is applied and the bolt breaks.
Care should be taken to apply the force gradually and avoid applying excessive force that can lead to bolt failure.
