The Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii. We will use this geometry as a baseline in steering system geometry design.

     Before designing the steering system mechanism, we need to specify the width of the steering rack first. In this case, we use a steering rack from KAZTechnologies as a reference in steering rack dimension, which is 15.225 inches (386.715 mm) in width.

The hairpin turn is part of the FSAE competition, is considered the narrowest turn, and has an outside diameter of 9 m. So we will consider 3 m as the narrowest radius the car can turn.
