WebMay 4, 2024 · As discussed, this is the definition of a reaction force. The roller can only push, so you know its definite direction (even the sign of it). A reaction force is then easily modeled as a force perpendicular to the object's surface where it contacts the roller. My bad about being so loquacious. Make sense? WebJul 28, 2024 · Normal Forces (or Reaction Forces): Every object in direct contact with the body will exert a normal force on that body which prevents the two objects from occupying the same space at the same time. Note that only objects in direct contact can exert normal forces on the body.
