Perhaps less force than a car's steering, but a much more rapid cycling of that force.
NTSB has a sophisticated ADAMS multi-body dynamics software and EASY5 system simulation software. In this simulation model NTSB is using “pilot’s controls have a small 5 lbf resisting force”.
The strength of the Control tubes and Rod Ends are much higher (at least 100 times higher) than this 5 lbf load.
