# Q.The fundamental equation for correct steering is (where φ and α = Angle through which the axis of the outer wheel and inner wheel turns respectively, c = Distance between the pivots of the front axles, and d = Wheel base)

• Asinφ + sinα = b/c
• Bcosφ - sinα = c/b
• Ccotφ - cotα = c/b
• Dtanφ + cotα = b/c
Correct Answer : (C)

cotφ - cotα = c/b
