Define camber, caster, and toe angles and explain their primary effects on tire grip and handling.

Describe how suspension geometry changes during vertical wheel travel (bump and droop).

Explain the concepts of bump steer and roll steer and their impact on vehicle stability.

Describe how suspension geometry changes as the vehicle body rolls (camber gain).

Describe the geometry and primary kinematic characteristics of double wishbone suspension.

Describe the geometry and primary kinematic characteristics of MacPherson strut and multi-link suspensions.

Compare double wishbone, MacPherson strut, and multi-link suspensions based on camber control, packaging, and typical applications.

Explain longitudinal and lateral load transfer using a conceptual force balance.

Explain how spring rate and motion ratio combine to determine the effective wheel rate.

Describe the role of dampers in controlling suspension oscillations and transient vehicle behavior.

Describe how anti-roll bars function to manage body roll and adjust handling balance.

Explain the function of a third spring (heave spring) in controlling the aerodynamic platform of a race car.

Explain the operation of pushrod and pullrod systems for actuating inboard spring-damper units.

Describe the packaging and aerodynamic advantages of using inboard suspension systems.

Describe how aerodynamic loads (downforce) influence suspension design choices and setup parameters in F1 and IndyCar.

Explain how rockers can be used to create a non-linear motion ratio.

Compare the typical suspension architectures (e.g., double wishbone vs. multi-link) and actuation methods (direct vs. pushrod/pullrod) used across F1, IndyCar, and high-performance road cars.

Compare suspension travel and ride height requirements across the three vehicle types, linking them to aerodynamics and operating environments.
