Kinetic energy of the cantilevers can be calculated assuming that it is a portion of the sine curve or as an absolutely rigid straight line: outcome within the set accuracy is the same.
In this case, the appropriate polynomial approximation can be individually and nicely fitted to each sine curve segment.
For the period from the maximum to the transition point, the sine curve used is sometimes treated as a the second quadrant of the same sine curve used for the period up to the maximum (Parton and Logan 1981; Goudriaan and van Laar 1994), although others have preferred a separate sine curve with a different phase length for this section (Cesaraccio et al.

During this time, supply operations usually underwent a steep ramp-up phase, which extracts a tremendous amount of effort from the crew to climb back to the top of the readiness sine curve.
The high points of the sine curve rotor are always in contact with, or in close proximity to, the liners and scraper gate, assuring low slip and a powerful suction lift.
Toward this end, the spurs emanating from a multiple-bit DRFM that approximates a sine curve in an ideal "least-squares" sense are analyzed.
When VFDs are used in electric induction motors, power is no Ionger provided in a balanced, three-phase sine curve, but in controlled pulses (Figure 4), referred to as square-wave or sixstep voltage.
