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 held in place, 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 helps engineers ensure that components, such as bridges and mechanical parts, can withstand the forces they encounter during use.
