Analysis and Procedures for Material Selection

The term material selection means to select the right material for various engineering applications. There are various engineering materials available and each has different individual properties. Thorough knowledge of the material properties and behavior is crucial in the design process. For instance, a structural member, such as a beam, is used to support vertical shear loads by the building itself. To withstand such loads, the material of the beam must possess adequate strength and stiffness to resist any deformation that might lead to the formation of cracks.

1.) Determine the force in each member (and identify whether it is compression or tension) of the truss supporting a floor deck as shown. The deck is simply supported on floor beams which, in turn, are connected to the joints of the truss.
