Answer to Question #176149 in Civil and Environmental Engineering for Sibongile Mwenge

Question

the difference in level between and bottom of a railway embankment was found to be 15.216m. the length of the embankment was measured during its surface as 25.214m using a steel tape under a pull of 25N at a temperature of 10 °c . at the tape standarulized on the flat at 20°c under a pull of 49N. what is the embankment gradient? the cross sectional area of the tape is 6.5mmsqured,E=20.8x10^4MN/m^2 and a=1.1x10^-5 per °c

Answer 1

gradient= difference in height/difference in width

= 15.216/25.214

= 0.6035
