3. A civil engineer used a 30-m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long. The difference in elevation between the initial point and the end point was found to be 1.25 m. The 30-m tape is of standard length at a temperature of 10°C and a pull of 50 N. During measurement the temperature reading was 15°C and the tape was supported at both ends with an applied pull of 75 N. The cross-sectional area of the tape is 6.50 mm2 and the modulus of elasticity is 200 GPa. The tape has a mass of 0.075 kg/m. coefficient of thermal expansion is 0.0000116 /°C. Determine the total correction per tape length due to temperature, pull and sag only.

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). ● (ii). The sand is dry, with a dry unit weight y = 17 kN/m³, and friction angle ' = 35º. (642.7 kN = 65.5 ton) The sand to the right of the vertical dashed line is saturated, with a saturated unit weight Ysat = 20 kN/m³ and friction angle = 35º.

Jisoo used a 40 meter steel tape in measuring an inclined distance on a gentle slope. The sloping distance was recorded to be 440 meters long. The difference in elevation between the initial point and the end point was found to be 32.49 m. The 40-meter tape is of standard length at a temperature of 20 °C and a pull of 34 N. During measurement, the temperature reading was 44 °C and the tape was supported throughout its length with an applied pull of 82 N. The cross-sectional area of the tape is 1.54 mm^2 and the modulus of elasticity is 200 GPa. The tape has a mass of 0.68 kg. Determine the corrected horizontal distance in meters. Round off to two decimal places.
