WebThe normal force is the force exerted by a surface that pushes on an object out, perpendicular to the surface in response to the object’s pushing into the surface. The normal force prevents the object from penetrating the surface. In equation form, the force of … WebUsing the parallel-axis theorem eases the computation of the moment of inertia of compound objects. We see that the moment of inertia is greater in (a) than (b). This is because the axis of rotation is closer to the center of mass of the system in (b). The simple analogy is that of a rod. Web12 feb. 2024 · There may also be a similarity to some switched reluctance motor designs. To determine the number of poles in the rotor, count the number of poles by carefully moving a magnet around the inside circumference and noting attractions and repulsions. Take note of Bruce Abbott's advice about the possibility of demagnetizing with a strong magnet. our flag means death prime
