Constant force “A steady force in a single direction for example the resistance you feel when you’re turning into a corner.” – Microsoft.com
Ramp force “A force that steadily increases or decreases in magnitude, for example, the resistance of the weight of the car and you transfer the weight of the chassis in a corner. A ramp force might be felt more strongly in a car with a lot of caster in the steering angle.” – Microsoft.com
Periodic effect “A force that pulsates according to a defined wave pattern, for example, if you’ve damaged the car sometimes the simulator software will add a vibration through the steering wheel.” – Microsoft.com
Constant force. A steady force in a single direction. Ramp force. A force that steadily increases or decreases in magnitude. Periodic effect. A force that pulsates according to a defined wave pattern. Condition. A reaction to motion or position along an axis. Two examples are a friction effect that generates resistance to movement of the joystick, and a spring effect that pushes the stick back toward a certain position after it has been moved from that position.
