The principle of direct contra bending manipulation technique is the fact that we need higher energy or force to withstand resistance or the curve load in order to realign the bent spinal curve which can be obtained by two methods, namely, to decrease the curve resistance force or to increase the force to straighten the curve.
Forces acting on the coupler are extremely complex and include train resistance (friction, air), grade resistance (lifting the weight in an ascending grade) and curve resistance (friction between the wheel flange and rail on curves) as well as the trailing tons represented by the other cars.
