The Vibrating StringA string of length . is fixed at both ends. Thereby appear forces . that are constant in time and independent of the position. The string tension acts as a backdriving force when the string is displaced out of the rest position. In this chapter, we discuss the resulting vibrational motion of the string.

Newton’s Equations in a Rotating Coordinate System However, this is no longer valid if a system undergoes accelerations. The new relations are obtained by establishing the equations of motion in a fixed system and transforming them into the accelerated system. In this chapter, we will look in detail at a special class of accelerated systems: We will discuss Newton’s equations in rotating systems.

Center of Gravity as proportional to the sum of position vectors, weighted with the respective masses. The center of gravity is an extremely useful concept to simplify the discussion of the dynamics of systems consisting of many particles.

Rotation About a Pointeorem. If the origin of the body-fixed coordinate system is set at the center of gravity of the body, one can separate the center-of-mass motion and the rotation in all practical cases. For this reason, the rotation of a rigid body about a fixed point is of particular significance.

In the general case the rotation axis will change its orientation too. The meaning of the six degrees of freedom becomes clear once again: The three translational degrees of freedom give the coordinate
