In Figure 6 the polar diagram of stress is presented.
7 and 8 there are the diagrams of forces loading the bearing neck as well as the polar diagram of force loading the base bearing (Bobescu, 1997).
The polarizer was rotated in 20[degrees] steps and a polar diagram was constructed for the 4623-4608 [cm.sup.-1] absorption bands (Fig.
A simple way to view amplitude and phase is with a polar diagram shown in Figure 1.
The polar diagram confirms the strong performance; on the wind in 12 knots true, the curves show about 7.3 knots of boatspeed.
At the other end of the scale, Rod reports 4 knots of boatspeed in about 6 knots true (the polar diagram shows 3.9).
Azimuthal variations of HVNR are presented on rectangular and on polar diagrams for five elaborated points.
We saw 5.8 knots on the wind in 9.6 knots true, a figure supported by the polar diagrams. In a 20-25 knot breeze, Team Windcraft recorded 9.6 knots reaching under the asymmetric.
Figure 7 shows the polar diagrams obtained from Hsu-Nielsen sources applied on a PMMA plate.
For the representation of the polar diagrams at constant magnetic flux density, an original program was developed to interpolate the experimental results, in order to obtain the same vector of the magnetic flux density for all the measuring directions.
The polar diagrams show that she needs 15 knots of breeze to reach 6 knots of boatspeed at 36 degrees, but as the wind builds the Harmony's upwind performance curve increases quite steeply.
