What is the proper term to indicate how much force the driver needs to exert to steer the wheels of a car?

The force required for the driver to turn the steering wheel would be a torque measured in foot-pounds (or Newton-meters).

Extra Credit: The actual force required for the rack in a rack and pinion style steering system to push/pull the tie-rods to turn the wheels would be a simple load measured in pounds or kilograms. The actual load the tires experience when trying to turn would again be a torque.

    Well, those are the units of measurement, not the actual term. Unless that's what the OP was asking. – I have no idea what I'm doing Jun 23 '16 at 10:11
  • @IhavenoideawhatI'mdoing Torque is the "term to indicate how much force" as OP requested, ft-lb is the unit of measurement. – MooseLucifer Jun 23 '16 at 13:06

    Sorry, my question was indeed unclear, I was looking for the actual term and not the unit. However, it's nice to know the unit as well :) Also, thanks for the extra credit! – Franck Dernoncourt Jun 23 '16 at 15:23

I've heard the term "steering effort" used, seems appropriate. It's not quantifiable, but it gets the idea across.
