• energy | Definition, Types, Examples |

    Energy can be neither created nor destroyed but only changed from one form to another. This principle is known as the conservation of energy or the first law of thermodynamics. For example, when a box slides down a hill, the potential energy that the box has from being located high up on the slope is converted to kinetic energy, energy of motion.

  • Differential Equations Mechanical Vibrations

    Mechanical Vibrations. We are going to start with a spring of length l, called the natural length, and we're going to hook an object with mass m up to it. When the object is attached to the spring the spring will stretch a length of L . We will call the equilibrium position the position of the center of gravity for the object as it hangs on the spring with no movement.

    Then, if a floor has a frequency equal to the natural frequency, the vibration is amplified and transmitted to the equipment. Then, the passive vibration is only available in the region over square root of 2 times fn. If one tries to reduce the natural frequency of the passive vibration isolator, it becomes compliant.

  • How Does A Viscous Damper Work?

    Torsional vibration is the speed fluctuation of a rotating shaft. [It] can have two components, twist and rigid body motion. Twist is the kind of vibration that is expected when you think of crankshaft torsional vibration. From one end of the shaft to another the vibration amplitudes change direction.

    Mar 20, 2011· The conductor vibration results in cyclic bending of the conductor near hardware attachments, such as suspension clamps and consequently causes conductor fatigue and strand breakage. When a "smooth" stream of air passes across a cylindrical shape, such as a conductor or OHSW, vortices (eddies) are formed on the back side.
