Question 81

Multiple Choice

A 10-pound weight is lying on a sit-up bench at the gym. If the bench is inclined at an angle A 10-pound weight is lying on a sit-up bench at the gym. If the bench is inclined at an angle , there are three forces acting on the weight, as shown in Figure. 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.
