A ball of dough is rolled into a flat chapatti. Name the forceexerted to change the shape of the dough

The force exerted to change the shape of the dough into a flat chapatti is primarily known as deformation force or external force. In this context, the process involves applying pressure and manipulation to the dough, which can be classified as a mechanical force. When you roll out the dough, several forces act on it, including the force applied by the rolling pin and the weight of the dough itself.

In more technical terms, this process involves two key types of mechanical forces:

1. Compressive Force: When the rolling pin presses down on the dough, it generates a compressive force that causes the dough to flatten.
2. Shear Force: As the rolling pin rolls over the dough, it applies shear forces that cause layers of dough to slide over one another, further aiding in flattening and shaping the dough.

Overall, the deformation of the dough results from the combination of these forces, which alters the material properties of the dough, making it pliable and allowing it to take on the desired flat shape of a chapatti. This transformation is a practical demonstration of how applied forces can change the shape and structure of materials.
