Torsion refers to the twisting of an object due to an applied torque. This phenomenon occurs when a force is applied at one end of an object while the other end is fixed, causing the material to twist around its axis. Torsion is commonly observed in structures like beams and shafts, where it can affect their strength and stability. In engineering, understanding torsion is crucial for designing safe and effective structures. Materials respond differently to torsion, with some being more resistant to twisting than others. The study of torsion is essential in fields such as mechanical engineering and civil engineering, where it helps ensure that structures can withstand various forces.
