Wheel motion to A-frame tilt

The antenna was moved such that wheel 1 rolled over 2 shims and wheel 2 rolled over one, and the tilts of the Right A-frame were measured by the inclinometers (see Fig.10). The measured tilts were 2.45, 2.81, and 2.89, respectively, giving a mean of 2.72 + 0.23, compared with an expected 2.96. Within the errors these data are consistent, or yield a transmission of wheel motion to A-frame tilt of 0.92 + 0.10. (We must assume that such relations hold for the L-Aframe also - we did not repeat these experiments for that side of the antenna.)
