... Answer [B]: By Newton’s third law, the force exerted by the rod on the hinge is the same as the force exerted by the hinge on the rod, G which I will denote Fh . From the geometry of the problem, since the rope is at a 45° angle from the rod, in the coordinate system shown, Tx = −Ty The rod is in eq ...

Today in Physics 217: electric dipoles and their interactions
... If the dipole moment is constant, the net force is zero, because the charges get pulled equally and oppositely. There is a torque, though, that tends to align the dipole moment vector with the applied field: x ...

Ch 8 Rotational Motion and Equilibrium
... • The figure on the left below shows that a force acting in a direction that is directly toward or away from the axis of rotation will cause no rotation. That is, radial forces produce zero torque. • The figure on the right below shows that if the force is at an angle θ relative to the radial line, ...

Translational_Equilibrium
... • Equilibrium is the state of a body in which there is no change in its motion. • A body is in equilibrium when the net force acting on it is zero; there is no acceleration (a = 0 m/s2), the body is either at rest or is moving at a constant velocity. • The study of objects in equilibrium is called ...

Chapter 21 Rigid Body Dynamics: Rotation and Translation
... We shall analyze the motion of systems of particles and rigid bodies that are undergoing translational and rotational motion about a fixed direction. Because the body is translating, the axis of rotation is no longer fixed in space. We shall describe the motion by a translation of the center of mass ...
