Can the Normal Force Produce a Torque on an Object on an Incline?

In summary: This difference in stress causes a net torque around the center of the square.In summary, the conversation discusses the concept of normal force producing torque on inclines and how it applies to square shapes on friction surfaces. The participants also consider the role of internal stress and its effect on torque. A diagram is requested to better understand the scenario.

Hi everyone I can't understand how normal force produce torque isn't normal force acts normally on the plane so the perpendicular distance in case if it was like block will be zero, so normal force doesn't produce torque. "case of box"

Are you referring to internal stress?

Depends on the friction I think

Here's a geometry question for you: If you have a line tangent to a circle, the normal to the line at the point of tangency passes through the center of the circle. True of False.

Who says that the normal force results in a torque about the center of the square?

How square in friction surface have net torque of zero

Internal "torques" exist in the form of stress.
 
  • #14
But internal torques comes in pair so they cancel each other

As @dsaun777 indicates, if friction is present, the normal force is not distributed uniformly over the base of the square, and the normal stress is greater near the downward edge than near the upper edge on the base.
 

1. Can the normal force produce a torque on an object on an incline?

Yes, the normal force can produce a torque on an object on an incline. This is because the normal force is perpendicular to the surface of the incline, and when combined with the weight of the object, it creates a torque that causes the object to rotate.

2. How is torque affected by the angle of the incline?

The torque produced by the normal force on an object on an incline is directly proportional to the angle of the incline. The greater the angle of the incline, the greater the torque produced.

3. Does the weight of the object affect the torque produced by the normal force?

Yes, the weight of the object does affect the torque produced by the normal force. The greater the weight of the object, the greater the torque produced.

4. Is the normal force the only force that can produce a torque on an object on an incline?

No, the normal force is not the only force that can produce a torque on an object on an incline. The weight of the object and any other external forces acting on the object can also contribute to the torque.

5. Can the normal force produce a torque on an object on a frictionless incline?

Yes, the normal force can still produce a torque on an object on a frictionless incline. This is because the normal force is still perpendicular to the surface of the incline and can still combine with the weight of the object to create a torque.
