the difference in level between the top and bottom railway embartment was found to be 15.216m. the length og embankment was measured along its surface 25.214m using a steel tape under the pull of 25N at a temperature of 10°c if the tape was standardized on the flat at 20°c under a pull if 49°c , What is the embankment gradient?
Two concentric springs, the central spring being 5 mm shorter than the outer spring, are to be loaded as shown. The outer spring consists of 40 turns of 15 mm diameter wire coiled on a mean diameter of 100 mm. The central spring, on the other hand, has 80 turns of 20 mm diameter wire coiled on a mean diameter of 80 mm. Use 83 GPa and 76 GPa for the shear modulus of the outer and the central springs, respectively. If the load P = 2 kN, determine the stress in the central spring and the displacement of the plate.
