3. A 30-m steel tape that is standardized at a temperature of 18°C and under a pull of 8 kg. The measured length of a line using this tape was 1602 m under a pull of 12 kg. The temperature during the measurement was 26°C. The tape was supported only at the ends of every 30 m length during the measurement. The tape has a cross-sectional area of 0.04 cm², Modulus of Elasticity of 2.1 x 106 kg/cm², coefficient of thermal expansion of 0.000012/°C, and a unit weight of 0.0077 kg/cm'. Determine the corrected length of the line.

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.
