  2. Kinematic pair - Wikipedia

    en.wikipedia.org/wiki/Kinematic_pair

    A screw joint or helical H joint requires cut threads in two links, so that there is a turning as well as sliding motion between them. This joint has one degree of freedom. A cylindrical C joint requires that a line in the moving body remain co-linear with a line in the fixed body. It is a combination of a revolute joint and a sliding joint.

  3. Frequency - Wikipedia

    en.wikipedia.org/wiki/Frequency

    A pendulum with a period of 2.8 s and a frequency of 0.36 Hz. For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term frequency is defined as the number of cycles or repetitions per unit of time.

    Examples of canonically conjugate variables include the following: Time and frequency: the longer a musical note is sustained, the more precisely we know its frequency, but it spans a longer duration and is thus a more-distributed event or 'instant' in time. Conversely, a very short musical note becomes just a click, and so is more temporally ...

  8. Degrees of freedom (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Degrees_of_freedom_(mechanics)

    An example of a simple open chain is a serial robot manipulator. These robotic systems are constructed from a series of links connected by six one degree-of-freedom revolute or prismatic joints, so the system has six degrees of freedom. An example of a simple closed chain is the RSSR spatial four-bar linkage.
