In a laboratory test of a beam loaded by end couples, the fiber at layer AB as shown are found to increase 40 x 10 -3 mm while those at CD decrease 70 x 10 -3 mm in the 240-mm-gage length. Using E = 160 GPa, %3D determine the flexural stress at the bottom fiber. Answer must be in MPa. Given: a = 50 mm, b = 120 %3D mm, and c = 90 mm. %3D gage length a mm B. b mm D. c mm

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.
