1. PROBLEM 1. In a five trials of walking along 90 m. course on fairly level ground, a pacer for a survey party counted 51, 52.5, 51.5, 52.5 and 51.5 strides respectively. He then started walking an unknown distance XY in four trials which were recorded as follows: 88.5, 89, 88 and 87 strides. Determine the length of the line XY in meters.

2. PROBLEM 2. The length of a line AB measured with a 50 m. tape is 465.285 m. When the tape is compared with a standardized Invar tape, it is found to be 0.016 m. too long in almost the same conditions of support, tension and temperature that existed during measurement of the line. Determine the correct length of AB in meters. (CONSIDER 3- DECIMAL PLACES) (10 Points) Enter your answer
4. PROBLEM 4. The correct distance between two points A and B is 420.65 m. using a 100 m. tape that is X meter too long, the length to be laid on the ground should be 420.604 m. What is the value of X. (CONSIDER 4-DECIMAL PLACES) (10 Points) Enter your answer
5. PROBLEM 5. A 30 m. tape is supported only at its ends and under a steady pull of 8 kg. If the tape weighs 0.91 kg., determine the correct distance between the ends of the tape in meters. (CONSIDER 4-DECIMAL PLACES) (10 Points) Enter your answer
6. PROBLEM 6. The sag correction for a certain 100 m. tape, supported at the ends only is 0.24 m. When the same tape is supported at the ends and at the 50 m. mark, all other conditions remaining the same, compute the sag correction for one full tape length in meter.
