2. (10 pts) The ratio of steady state curvature 1/R to the steer angle (delta) can be used to evaluate the response characteristics of a vehicle. This ratio is called the curvature response. a) Determine an expression for this ratio as a function of L, K, V, and g. b) For a vehicle with L=120 in, plot curvature response [1/(ft*deg)] vs speed [mph] over the range o to 150 mph for (1) a NS vehicle, (2) an OS vehicle with K=-1.25 deg, and (3) an US vehicle with K=1.5 deg. Plot all three on the same axes. Note: for the OS vehicle, only plot speeds less than critical speed (by enough to get a decently scaled plot). 2.
