Subtopic: Calculation of power, torque, fuel consumption, heat load and power losses
Question Statement:
A tractor travels a distance of $45.0\text{ m}$ in $10\text{ revolutions}$ of its rear drive wheels under zero-slip (no-load) condition on concrete. When pulling a heavy subsoiler in a tilled field, the tractor advances only $36.0\text{ m}$ in the same $10\text{ revolutions}$ of the drive wheels. Calculate the wheel slip as a percentage.
