This type of bar is called an axially loaded bar. When the bar isprismatic, homogenous, and isotropic and the applied load acts through the centroid of the cross section, the regions of the bar that are not near theapplied loads will deform uniformly. Many common engineering materials, such as steel, aluminum, and other metals can be treated ashomogenous and isotropic. Other materials like wood and composites are not necessarily homogenous or isotropic. In those cases, the deformationmay not be uniform and more detailed methods of analysis are required. A section is "near" an applied load when it is closer to the load than thelargest dimension of the cross section of the member.-F3For the following questions, consider the metal axial member shown in the figure below. Assume that applied loads are such that they act axially atthe centroid of the cross section (i.e., the total axial load acting at the centroid at on the leftmost flange would be 2F, and the total axial load actingat the centroid at section C would be 2F3).F₂F₁F₂ABCF3D EF
