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.
Another word for stresses that can push, pull, bend, or twist structures is "mechanical forces." These forces can include tension, compression, shear, and torsion, which all play a crucial role in determining how materials and structures behave under different loads.

an example is a ruler being twisted between both hands
Under vehicle, by end of torsion bar not attached to control arm.
Under torsion only, the shear stress is minimum, in fact zero, at the center point ( where radius is zero)
Under vehicle by end of torsion bar (side closer to rear of vehicle) there should be a 6-point bolt which when tightened or loosened will apply more or less tension to torsion bar.
Look under the hood & see if present.
The five forces that occur in structures are compression (pushing together), tension (pulling apart), bending (combination of compression and tension), shear (sliding forces acting parallel to each other), and torsion (twisting forces). These forces need to be considered in the design and analysis of structures to ensure their stability and safety.
Prefabricated structures are structures that are pre-made in a factory and there is no assembly required. Some examples would be a car or scooter.
