Tractive Force Calculator

Yaw rate (ψ):

Vehicle's forward velocity (v):

Wheelbase (L):

Steering angle (δ):

Gravitational acceleration (g):

Turn radius (R):

How This Is Calculated

$$ \psi = \frac{v}{L} \left( \frac{\delta}{1 + \frac{v^2}{gR}} \right) $$ where:

ψ = Yaw rate (rad/s)

v = Vehicle's forward velocity (m/s)

L = Wheelbase (m)

δ = Steering angle (rad)

g = Gravitational acceleration (m/s²)

R = Turn radius (m)

Assumptions

Dynamic load transfer is not considered.
The vehicle is treated as a rigid body with no suspension effects.
Tyre characateristics are ideal.
Road surface and load effects are neglected.
