A 10-pound weight is lying on a sit-up bench at the gym. If the bench is inclined at an angle of 
, there are three forces acting on the weight. N is called the normal force and it acts in the direction perpendicular to the bench. F is the force due to friction that holds the weight on the bench. If the weight does not move, then the sum of these three forces is 0.
