Farm Power

Subtopic: Traction theory

Question Statement:

Bekan equation in terramechanics describes the sinkage ($z$) of a wheel in soil as a function of ground contact pressure ($p$) by:

Options:

  • (A) $p = \left( \frac{k_c}{b} + k_\phi \right) z^n$
  • (B) $p = k z$
  • (C) $p = \frac{z}{k_c + k_\phi}$
  • (D) $p = k_c b z^2$

Answer Key:

A

Step-by-Step Solution & Explanation

Bekker's pressure-sinkage relationship models cohesive ($k_c$) and frictional ($k_\phi$) soil sinkage modulus.
