Bar ABC has an outer diameter of 10 mm and is made of red brass for which E = 100 GPa. Section AB is hollow with a wall thickness of 2 mm and section BC is solid. Knowing that P is 26 kN, applied to both sides of the bar at B and Q is 5 kN, applied to the bar at C as shown. What is the total %3D change in length of bar ABC? Express your answer in mm, to the nearest 0.01 mm, taking elongation as positive and contraction as negative. A B C 400 mm - 600 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.
