If the inner and outer steering angle in a tractor are 9° and 9.8° respectively then for correct steering conditioning the value of the ratio of pivot axis spacing to track length is equal to ______
a) 0.256
b) 0.525
c) 0.990
d) 0.756

Answer: b
Explanation:θ = 9.8°
Φ = 9.0°
We know that,
Cot θ – Cot Φ = \(\frac{c}{b} \)
-Cot (9.8) + Cot 9 = \(\frac{c}{b} \)
-5.789 + 6.314 = \(\frac{c}{b} \)
\(\frac{c}{b}\) = 0.525.
