Maximum grade angle from tractive force

Calculates vehicle acceleration from tractive force, resistance force, and vehicle mass.

Calculates the force needed to overcome a grade from vehicle mass and slope angle.

Calculates tractive force from engine torque, total ratio, drivetrain efficiency, and rolling radius.

Calculates tire contact tractive force from wheel torque and rolling radius.

Solves drivetrain efficiency from input and output power.

Calculates engine rotational speed from vehicle speed, total ratio, and rolling radius.
