Question 2 The bulldozer shown in the Figure below is fitted with a blade, 1.1 m high and 5 m wide. What weight must the bulldozer be such that it can push the sand forward (to the right, as shown) without the tracks slipping on the underlying sand (with a Factor of Safety of 1.3)? Assumptions: • The friction angle (8) between the bulldozer tracks and the sand is equal to 0.6 x *'. • The "side friction" (front and back sides between the block of sand that is being moved, and the sand on either side of the blade that stays behind) can be ignored. Do this calculation for the following two cases: (i). The sand is dry, with a dry unit weight y = 17 kN/m³, and friction angle = 35º. (642.7 kN = 65.5 ton)
