Direction of rotation of moment

In summary, the conversation discusses the direction of rotation and moment in a scenario involving the M2 and M1 parameters. The right hand grip rule is mentioned as a guide for determining the direction. However, the book presents the direction in a different way, which may be inconsistent but ultimately not relevant to the main point.

Homework Statement


IMO , the M2 and M1 should rotate clockwise, and the moment should point downwards based on right hand grip rule . Why the book gave in in other way ?

I don't think you are supposed to take the arrow directions as accurate. They are merely indicating which entities are forces and which are couples.

you mean the author just simply give the direction of moment ?

No, I'm saying that the author did not care about being consistent. It was not relevant to the point being made.
 

FAQ: Direction of rotation of moment

What is the direction of rotation of moment?

The direction of rotation of moment is the direction in which a force tends to cause an object to rotate. It is typically described using the right-hand rule, where the fingers of your right hand curl in the direction of the force and your thumb points in the direction of rotation.

How is the direction of rotation of moment determined?

The direction of rotation of moment is determined by the direction of the force and the position of the force relative to the object's axis of rotation. The direction of rotation is perpendicular to both the force and the axis of rotation.

Does the direction of rotation of moment depend on the direction of the force?

Yes, the direction of rotation of moment is dependent on the direction of the force. Reversing the direction of the force will also reverse the direction of rotation.

Can the direction of rotation of moment be changed?

Yes, the direction of rotation of moment can be changed by changing the direction of the force or by changing the position of the force relative to the object's axis of rotation.

Why is the direction of rotation of moment important?

The direction of rotation of moment is important because it determines the direction in which an object will rotate in response to a force. This is crucial in understanding and predicting the behavior of objects in motion, and is particularly important in engineering and physics applications.
