1. (b) A wheeled tractor has a combined loading on the rear driving wheels of 2.65 tons and each wheel has a contact area of 0.11 m² and contact length of 400 mm. It operates on a soil with cohesion, c= 5 kN/m², angle of internal friction, 6 = 29° and soil deformation modulus, K = 35 mm. Assume that the acceleration due to gravity is 9.81 m/s i) iii) iv) Estimate the ideal maximum thrust, Hmax. Find the slip when the soil thrust, H = 8 KN (Use a - JA the tables provided). Comment on the result obtained from Question 1(b)(ii). What will happen to the slip when there is a 50 per cent increase in wheel contact length?
