Developed Equation for Steer Angle
Abstract — This paper deals with the steering mechanism in detail. As the design component, various equations were derived from the fundamentals. A computer program was made on C language, which calculates all the data relating to steering i.e. (Ackermann angle, length of tie rod, steer angle).
The program was simulated under different Ackermann angle, and various inferences were drawn from it. CAD models were also created to demonstrate the various components used in steering systems.

PRINCIPLE
The relative motion between the wheels of a vehicle at the road surface should be of a pure rolling type so that wear of the tires is minimum and uniform. When the vehicle is moving on a curved path, as shown in Fig 2, the steering gear must be so designed that the paths of the point of contact of each wheel with the ground are concentric circular arcs. For proper steering the axis of rotation of all the wheels should meet at G i.e. the instantaneous center of rotation of the vehicle. To satisfy this, the inner wheels should be turned through a greater angle as shown in Fig in which ? is greater than ∅, ?ℎ?? the vehicle is turning towards the right side.
INTRODUCTION
The intention of the steering arrangement is to permit the driver to manipulation the association of the vehicle by curving the wheels. This is completed by way of steering wheel, a steering column that transmits the rotation of the steering wheel to the steering gears, the steering gears, that rise the rotational power of the steering wheel so as to send larger torque to the steering linkage, and the steering linkage that transmits the steering gear movement to the front wheels (See Fig 1) . The steering arrangement configuration depends on vehicle design (the drive train and suspension
