The composite beam shown in the Figure 1 is constructed from wood and reinforced with a steel strap at the top and the bottom with two rows of nails spaced every 105 mm. If a shear force of V=1,874 kN is applied to the beam, determine the shear force (in kN) resisted by each nail. Take Est = 200 GPa, Ew = 15 GPa.

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.
