1. The figure below shows a roof canopy beam which is supported by a φ20 mm hanger rod. The  roof beam is a W200×19 steel beam with a cross-sectional area A = 2480 mm2, section modulus,  Sx = 163×103 mm3 and a moment of inertia Ix = 16.6×106 mm4. The modulus of elasticity for  steel is 200 000 MPa.  1)     Determine the beam reactions at A and B.      2)     Determine the axial stress in the 20 mm hanger rod and in the W200x19 beam.     3)     Determine the shear force and bending moment   at the midspan of the beam

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.
