Summary

The length of a line AB measured with a 50-m tape is 465 m. When the tape is compared with a standardized invar tape it is found to be 0 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.A bui...

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.

A building 38 m by 45 m is to be laid out with a 5 -m g metallic tape. If during standardization the tape is found to be only 49.9 m, determine the dimensions to be laid out, using this tape, in order that the building shall have the desired dimensions.

Slope distance AB and BC measures 330.49 m and 660.97 m, respectively. The differences in elevation are 12.22 m for A and B, and 10.85 m for points B and C. Using the approximate slope correcti n formula for gentle slopes, determine the horizontal length of line ABC. Assume that the line AB has rising slope and BC a falling slope.

A steel tape with a coefficient of linear expansion of 0.0000116/°C is known to be 50 m long at 20°C. The tape was used to measure a line which was found to be 532.28 meters long when the temperature was 35° C. Determine the following: a. Temperature correction per tape length b. Temperature correction for the measured line c. Correct length of the line

A heavy 50-m tape having a cross-sectional area of 0.05 cm2, has been standardized at a tension of 5.5 kg. If E = 2.1 x 106 kg/cm2, determine the elongation of the tape if a pull of 12 kg is applied.

A 30-m tape is supported only at its end and under a steady pull of 8 kg. If the tape weighs 0.91 kg, determine the sag correction and the correct distance between the ends of the tape.

A 30-m tape is supported at midpoint and at its end and under a steady pull of 8 kg. If the tape weighs 0.91 kg. A line was measured 678.91 m. Determine the correct length of the line....
