You are to design a 10 tonne mobile factory for deployment on the Moon (note that g=1.62 m/s2 on the Moon) assuming the following lunar soil parameters: Density Soil Friction Modulus of Modulus of (kg/m?) cohesion angle cohesion of friction of (Pa) (0) soil soil deformation, deformation, kc (N/m"+1) ku (N/mn+2) 1520 170 35 1400 820000 Soil deformation exponent, n 1.0 Lunar regolith
3. Use the Reece earth-moving equation to calculate the digging forces required to shovel lunar regolith to using a bulldozing blade with the following characteristics: (20 marks) Symbol Y с Parameter Soil density Soil cohesion Soil friction angle Tool width Tool length Cutting depth Blade rake angle of approach Soil shear plane angle Soil-blade friction angle ф b L Value 1520 kg/m3 170 Pa 35° 2.5 m 4 m 0.5 m 80° 45+0/2 26° Z OUR a B 6
