Dynamics of Rotational Motions

Drehmoment
Drehmoment
Torque is an important quantity for describing the dynamics of a rotating rigid body. We see the application of torque in many ways in the world, such as ...
Berechnung des Nettodrehmoments
Berechnung des Nettodrehmoments
When a mechanic tries to remove a hex nut with a wrench, it is easier if the force is applied at the farthest end of the wrench handle. The lever arm is ...
Gleichung der Rotationsdynamik
Gleichung der Rotationsdynamik
Angular variables are introduced in rotational dynamics. Comparing the definitions of angular variables with the definitions of linear kinematic ...
Rollen ohne Rutschen
Rollen ohne Rutschen
People have observed the rolling motion without slipping ever since the invention of the wheel. For example, one can look at the interaction between a ...
Walzen mit Rutschen
Walzen mit Rutschen
Rolling with slipping is a physical phenomenon that occurs when a rolling object experiences both rotational and linear motion but also experiences ...
Arbeit und Kraft für Rotationsbewegungen
Arbeit und Kraft für Rotationsbewegungen
Work and power in rotational motion are completely analogous to work and power in translational motion. The total work done to rotate a rigid body through ...
Arbeitsenergiesatz für Rotationsbewegung
Arbeitsenergiesatz für Rotationsbewegung
The work-energy theorem for rotational motion is analogous to the work-energy theorem in translational motion. It states that the net work done by an ...
Drehimpuls: Einzelteilchen
Drehimpuls: Einzelteilchen
Angular momentum is directed perpendicular to the plane of the rotation, and its magnitude depends on the choice of the origin. The perpendicular vector ...
Drehimpuls: Steifer Körper
Drehimpuls: Steifer Körper
The total angular momentum of a rigid body can be calculated using the summation of the angular momentum of all the tiny particles rotating in the same ...
Erhaltung des Drehimpulses
Erhaltung des Drehimpulses
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Considering a system that consists of n ...
Drehimpulserhaltung: Anwendung
Drehimpulserhaltung: Anwendung
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Examples of such systems include a freely ...
Drehung der asymmetrischen Oberseite
Drehung der asymmetrischen Oberseite
By definition, a spherically symmetric body has the same moment of inertia about any axis passing through its center of mass. This situation changes if ...
Gyroskop
Gyroskop
A gyroscope is defined as a spinning disk in which the axis of rotation is free to assume any orientation. When spinning, the orientation of the spin axis ...
Gyroskop: Präzession
Gyroskop: Präzession
Precession can be demonstrated effectively through a spinning top. If a spinning top is placed on a flat surface near the surface of the Earth at a ...
