A small aluminum alloy [E = 79 GPa] tee shape is used as a simply supported beam as shown. For this beam, a = 155 mm. The cross- sectional dimensions of the tee shape are b = 16 mm, d = 24 mm, and t = 8 mm. After loads are applied to the beam at B, C, and D, a compressive normal strain of 410 µe is measured from a strain gage located at c = 9 mm below the topmost edge of the tee stem at section 1-1. What is the applied load P? P | 3P Strain gage- d D E H b

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.
