Which of the following is NOT a method of forming?

Laser forming is not commonly categorized as a traditional method of forming. The other options — hand forming, brake forming, and machine forming — represent conventional techniques used for shaping materials such as metals.

Hand forming involves manually manipulating materials to create specific shapes, which allows for high levels of customization and is often used for small-scale production or repair work. Brake forming utilizes a brake press to bend and shape sheet metal into desired angles and forms, allowing for precise control over the bends and has applications in various metal fabrication processes. Machine forming typically refers to the use of machinery to shape materials, which can include various industrial processes that maximize efficiency and consistency.

In contrast, laser forming is a more advanced and less common technique that employs laser energy to heat and deform materials. While it is a valid method within certain contexts, it does not fit into the conventional categories of forming techniques generally taught in basic structural mechanics courses.
