Correct option is B
A V notch is the most suitable notch for making a 90° bend in sheet metal or other materials. The V-shaped cut removes excess material at the bending point, making it easier to create a sharp and precise bend without distortion.
· The angle of the V notch is usually 90° or slightly greater, depending on the bending requirements.
· It ensures a clean and accurate bend without excessive strain on the material.
Purpose of Notching in Metalworking:
· Removes excess material to allow proper bending.
· Reduces stress and material distortion during bending.
· Helps in forming clean and precise corners.
