02 Second Order/Coupling Conditions/Traction
Traction
Traction names grip becoming available for movement. It is the contact condition through which carrying can proceed without slipping away from the support it needs. Traction is not mere connection or low resistance; it names enough resistance to let movement hold.
Trace
Read
Traction becomes recognisable where contact and grip support movement so that carrying can continue through resistance without detaching from support.
Structural Role
Traction is grounded movement through contact. It marks the usable middle between too little resistance, where carrying slips, and too much resistance, where carrying stalls.
