Wheel power from engine power

Solves drivetrain efficiency from input and output power.

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

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

Solves required engine torque from wheel torque, total ratio, and drivetrain efficiency.

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

Estimates maximum grade angle from available tractive force and vehicle mass.
