Torsional rigidity, or torsional stiffness, refers to a material's ability to resist twisting or torsional deformation when subjected to a torque. It is defined as the torque required to produce a unit angle of twist in a structural element. For example, a solid steel rod has high torsional rigidity, making it suitable for applications like drive shafts in vehicles, where it must withstand significant twisting forces without deforming. In contrast, a rubber rod has low torsional rigidity, making it inappropriate for such applications but suitable for dampening vibrations.

Torsion
Examples of torsion force include twisting a screwdriver to drive a screw into a surface, tightening a bolt with a wrench, and opening a bottle cap by twisting it. Torsion force occurs when an object is subjected to a twisting motion around its axis, causing stress and deformation in the material. This type of force is commonly seen in mechanical systems and structures where rotational motion is involved.
Torsion can be defined as two equal twisting forces acting on a body at two opposite sides. One of the best examples would be drying a wet towel by wringing it to remove excess water.
Torsion means twisting or being twisted. Intestinal torsion can be fatal.
ROD is used for axial loading and torsion, but BAR can be used for axial, torsion as well as bending loads....
A structure designed to withstand torsion is commonly referred to as a torsion-resistant member, such as a shaft or beam. These structures are typically made from materials with high shear strength and are often reinforced with additional supports or cross-sectional shapes, like I-beams or hollow tubes, to enhance their ability to resist twisting forces. Properly designed connections and load distribution are also crucial in preventing torsional failure.
Vehicle does not have torsion bars
Instead of using coil springs on the front suspension torsion bars are used from the lower control arms to the frame ( my 1995 Ford Explorer 4x4 has torsion bars , my dads 73 Dodge Coronet had torsion bars ) If you look at a lower front suspension that has torsion bars you will see the torsion bars going from the lower control arms rearward
