A steel tape is 30 m long at a temperature of 15°C and a pull of 50 N when laid on a flat surface. The tape weighs 18 N. It is stretched between end supports only allowing it to sag. Find the correct length of the tape at a field temperature of 25°C at a pull of 115 N. If in the above condition a base line is measured and the recorded length of the line is 600 m, find the correct length of the base line. Take a = 12 x 10-6 per °C and E = 2 x 105 N/mm². Sectional area of the tape = 7.50 mm².

Material Properties

Construction in civil engineering demands high strength, durability, and longevity. These targets can be achieved by better design and analysis, along with the correct choice of materials. Different materials have different properties and hence, they respond and performs differently under the various condition of external loadings. It is therefore a critical task of an engineer to select the right material based on the property that the material is supposed to function in real-time. When speaking about the property, there are different categories of material properties like chemical property, physical property, mechanical property, electrical property, magnetic property, thermal property, etc. These material properties form the basis of material selection in various applications.
