A line was recorded as 1750.00 meters long. The standard tape weighs 0.65 kg , 30.00m long at 20°C under a 50N pull. During the actual observation the temperature was 5°C and the tape was suspended under a 75N pull. It was also found that the tape is 3.00mm too long. If the line was inclined at 3%. E = 200GPa, A = 2.50mm² and the coefficient of linear expansion is 0.0000116 m/°C. (a) What is the actual inclined distance? (b) What is the actual horizontal distance.

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.
