Stocking rates are expressed as the number of animal unit months (AUM) supplied by one acre of land. The greater the difference between current forage production and the potential forage production of a pasture, the greater the difference will be between carrying capacity and recommended stocking rate.
The fundamental frequency of a wave is the lowest frequency (longest wavelength) that can be used to define its period. The easiest way to understand it is via a musical analogy: The fundamental frequency is the root tone of the overtone or harmonic series.
We define harmonics as voltages or currents at frequencies that are a multiple of the fundamental frequency. In most systems, the fundamental frequency is 60 Hz. Therefore, harmonic order is 120 Hz, 180 Hz, 240 Hz and so on.(For European countries with 50 Hz systems, the harmonic order is 100 Hz, 150 Hz, 200 Hz, etc.).We usually specify these orders by their harmonic number or multiple of the fundamental frequency.For example, a harmonic with a frequency of 180 Hz is known as the third harmonic (60x3 = 180). In this case, for every cycle of the fundamental waveform, there are three complete cycles of the harmonic waveforms.e usually specify these orders by their harmonic number or multiple of the fundamental frequency.
