It is apparent from Table 12-2 that the tensile strength of most materials is two to three
Question:
It is apparent from Table 12-2 that the tensile strength of most materials is two to three orders of magnitude smaller than Young?s modulus. Consequently, these materials, e.g., aluminum, will break before the strain exceeds even 1%. For nylon, however, the tensile strength and Young?s modulus are approximately equal. If a nylon line of unstretched length L0 and cross section A0 is subjected to a tension T, the cross section may be substantially less than A0 before the line breaks. Under these conditions, the tensile stress T/A?may be significantly greater than T/A0. Derive an expression that relates the area A?to the tension T, A0, and Young?s modulus Y.
