Subspace torque

From Memory Alpha, the free Star Trek reference.

Subspace torque is a force experienced by a starship traveling at warp speeds.

While experimenting with transwarp drive in 2372, Tom Paris, B'Elanna Torres, and Harry Kim found that as one approaches the transwarp threshold, subspace torque tore a nacelle from the ship. They learned that the subspace stress was acting on the ship body, not the nacelles, and that the solution was to create a depolarization matrix around the fuselage. (VOY: "Threshold")

The term 'torque' suggests this is a rotational force.
