ok, now I am lost... my base is the eigenvectors of [tex]L_z[/tex] how do i measure the values of moment in some direction [tex]n=(a,b,c)[/tex]?
fargoth said:but i can't obtain [tex]J_x[/tex] values at the same base as [tex]J_z[/tex]
The moment in science refers to the measure of a force's tendency to cause an object to rotate about a specific point or axis. It is calculated by multiplying the magnitude of the force by the distance from the point or axis.
The moment in a specific direction is measured by taking the cross product of the force vector and the position vector, and then taking the magnitude of the resulting vector. This will give the moment in the direction perpendicular to both the force and position vectors.
The unit of measurement for moment in science is typically Newton-meters (Nm) in the international system of units (SI).
The direction of the moment is determined by the right-hand rule, where the thumb of the right hand points in the direction of the force, the fingers point in the direction of the position vector, and the direction of the moment is perpendicular to both.
The concept of moment is used in many real-world applications, such as engineering and physics. It helps to determine the stability and equilibrium of structures, and is also used in the design of machines and tools to ensure the desired amount of force and rotation are achieved.
