A line is recorded as 472.90m long using a 30m tape. During measurement, the temperature is 32°C and the tape is laid on the ground under a 75N pull. The tape has the following properties: weight of 0.065kg/m, young modulus of elasticity is 200GPA, cross sectional area of the tape is 3mm? and the coefficient of linear expansion is 0.0000116/"C. The tape is 30.005m long at 40°C under a 20ON pull supported at both ends. Assume the standard pull is 50N, compute: a. The standard temperature in °C. b. The actual length of tape during measurement in meter. c. The true distance of the line in meter. If the survey are to be connected to the national mapping system of a country, the distances will need to be reduced to the common datum of the system, namely MSL (Mean Sea Level). The adjustment is expressed as H Reduction Factor = 1 R L' = L(1 d. If the height of measurement from the Mean Sea Level is 12km, determine the adjusted distance in meter.

The shown circular bar is fixed to the left wall. It has a diameter of 0.5 in and length of 60 in at 50 °F when it is unloaded. There is a gap of 0.08 inches between the bar end and the right opposite wall.
