How to specify the normal force for this example

In summary, the normal force is the force exerted by a surface on an object in contact with it, acting perpendicular to the surface and in the opposite direction of the applied force. It can be calculated by multiplying the object's mass by the acceleration due to gravity and the cosine of the angle between the surface and the vertical direction. The normal force can vary depending on the weight and angle of the object and the surface it is in contact with, and it is important to specify it in examples to determine stability, make accurate calculations, and predict the object's behavior. In some cases, the normal force can be greater than the weight of the object, such as when an object is being pushed against a surface.

1. The problem statement

Hi, I just have a quick question on how to find the normal force in this picture on mass 2, http://postimg.org/image/w9sr29ab3/ , the half circle. Its a double pendulum with no friction. Can I assume that the normal force is in that position all the time as the half circle goes back and forth.

thx for any help

Hello Chris, :welcome:

Could you please fill in the homework template? That way we have an idea what this is about !
 

Related to How to specify the normal force for this example

1. What is the normal force?

The normal force is the force that a surface exerts on an object that is in contact with it. It is always perpendicular to the surface and acts in the opposite direction of the force that is being applied to the object.

2. How do you calculate the normal force?

The normal force can be calculated by multiplying the mass of the object by the acceleration due to gravity (9.8 m/s^2) and the cosine of the angle between the surface and the vertical direction.

3. How does the normal force change in different situations?

The normal force can change depending on the weight and angle of the object, as well as the surface it is in contact with. If the object is on a flat surface, the normal force will be equal to the weight of the object. However, if the surface is angled, the normal force will be less than the weight of the object.

4. Why is it important to specify the normal force in an example?

Specifying the normal force is important because it helps determine the stability and equilibrium of an object. It also allows for accurate calculations and predictions of the object's motion and behavior.

5. Can the normal force be greater than the weight of an object?

Yes, the normal force can be greater than the weight of an object in certain situations. For example, if an object is being pushed against a surface, the normal force will be greater than the weight of the object as it is being supported by both the surface and the applied force.
