The material used for making torsion bar is Correct Answer All of the above

Torsion bars are a type of suspension component used in vehicles to provide resistance to twisting forces and support the vehicle's weight. They are typically made from various types of steel, including mild steel, treated steel, and high carbon steel. These materials are chosen for their strength, durability, and ability to withstand the torsional loads experienced during vehicle operation. Therefore, the correct answer is that torsion bars can be made from all of the above materials: mild steel, treated steel, and high carbon steel.
