A high-strength steel bar used in a large crane has a diameter d = 3.00 in. (see figure). The steel has a modulus of elasticity E= 29 x 106 psi and Poisson's ratio is y = 0.27. Because of clearance requirements, the diameter of the bar is limited to 3.002 in. when it is compressed by axial forces. What is the largest compressive load Pmax that is permitted? Assume that the material behaves linearly elastically. (Enter the magnitude in lb.)

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.
