an example is a ruler being twisted between both hands
Torsion
Examples of torsion force include the twisting of a screw to fasten objects together, the winding of a spring in a mechanical watch to store energy, and the turning of a key in a lock to disengage the mechanism.
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.
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
Spraining your ankle is typically caused by a torsion force, which is a twisting force that causes the ligaments in the ankle to stretch or tear.
The 1st generation Nissan Pathfinder, 1987 - 1995 had a torsion bar suspension on the front end of the vehicle. There is a driver's side and passenger's side torsion bar and they are not interchangeable. 1996 - 2009 models do not use a torsion bar.
A 2WD Tahoe does not have torsion adjustment bolts, it uses front coil springs and not torsion bars.
I'm pretty sure that only 4WD trucks have torsion bars.
