A towed pneumatic wheel has unloaded radius 330 mm and travels 9.9 m in five revolutions without skid. Taking rolling radius equal to static loaded radius, find wheel deflection in mm (one decimal).
Rolling circumference is 9900/5=1980 mm. Loaded radius is 1980/(2π)=315.13 mm. Deflection is unloaded minus loaded radius: 330−315.13=14.87 mm, or 14.9.
