I didn't find anything specific doing a search so I thought I'd ask this about warp engines: This might be specifically a TOS thing, but why do the warp engines start to threaten to overheat/burn out when the ship is grabbed by a generic tractor beam? I'm defining "generic tractor beam" by saying it grabs the ship like in "The Corbomite Maneuver" and "The Motion Picture" and the warp engines end up somehow fighting it. There are other tractor beam technology out there but they generally disrupt or immediately shuts down the power systems (like in "Arena" and "Relics") in which we have a known cause of what happened to the engines. Anyway, if the warp engines are just creating a warp field why would they start to overheat when the ship is grabbed? Are they overheating because they've lost subspace traction and are suddenly spinning out of control? Or are they overheating because the subspace traction is too great and they're overloading the "gears"?
