The design problem that the torque tube solves is how to get the traction forces generated by the wheels to the car frame.

In contrast, the Hotchkiss drive has the traction forces transmitted to the car frame by using other suspension components such as leaf springs or trailing arms.

In addition to transmitting the traction forces, the torque tube is hollow and contains the rotating driveshaft.

Microfabrication of microposts and measurement of their deflection can determine traction forces exerted on cells.

The power expended to move a vehicle is the product of the traction force of the wheels and the velocity of the vehicle.

As the tire rotates it exerts a high traction force to accelerate the vehicle and maintain its speed under constant velocity.

These tendons can sustain traction forces thanks to their collagen fibers.

This generates a traction force to oppose the motion of the vehicle.

An ankle strap may be fashioned from cloth, and tied or twisted to apply traction force.

It also provides a more comfortable ankle strap and a small winch that makes it much easier to apply and adjust traction force.
