Technician A says that camber and SAI make up the included angle. Technician B says the purpose of the turning angle is to reduce tire scuffing during cornering. Who is correct?

The statement is accurate because both technicians highlight important aspects related to vehicle dynamics and wheel alignment.

Technician A's comment on camber and Steering Axis Inclination (SAI) is pertinent as these angles are integral to determining the included angle in vehicle alignment. The included angle represents the relationship between the wheel's vertical alignment and how it interacts with the road surface during motion. This angle significantly influences vehicle handling, tire wear, and stability. Therefore, recognizing that camber and SAI contribute to the included angle is a valid assertion.

Technician B discusses the turning angle's purpose, which is critical during cornering. The turning angle is associated with how wheels pivot during a turn, affecting the vehicle's path and reducing tire scuffing. Proper management of the turning angle ensures that the tires maintain optimal contact with the road surface, minimizing undesirable wear and maximizing cornering capability. This optimization enhances overall steering responsiveness and stability.

Thus, both technicians present accurate insights into the principles of suspension and steering, making this an instance where both are indeed correct.
