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 m and contact length of 400 mm. It operates or a soil with cohesion, e - 5 kN/m, angle of internal friction, $ = 29" and soil deformation modulus, K 35 mm. Assume that the acceleration due to gravity is 9.81 m/s D) ii) Estimate the ideal maximum thrust, Hras Find the slip when the soil thrust, H=8 KN (Use a-Jathe tables provided) Comment on the result obtained from Question 1(b) (i). What will happen to the slip when there is a 50 per cent increase in wheel contact length? iv)
