Resistencia de materiales: Esfuerzos térmicos problema 4-68 Hibbeler

*4-68 The C83400-red-brass rod AB and 2014-T6- aluminum rod BC are joined at the collar B and fixed connected at their ends. If there is no load in the members when T1 = 50°F, determine the average normal stress in each member when T2 = 120°F. Also, how far will the collar be displaced? The cross-sectional area of each member is 1.75 in2. Link para propiedades: https://bit.ly/2kqAAA5
