Answer: Because when straightened it is not enough to withstand the force, when twisted it can withstand the force
Because when straightened, it is not enough to withstand the force, but when twisted, it can withstand the force. This is due to the difference in the material's response to the type of stress applied. When the object is straightened, it experiences a tensile stress along its length, which may exceed its tensile strength, causing it to break or bend. However, when twisted, the force is distributed across the structure in a way that allows the material to resist deformation better. This is because twisting introduces shear stress, which the material may be more capable of handling, depending on its properties and design. This is why many structural elements are designed to handle torsional forces rather than pure tension or compression.
