4-53. The assembly consists of two 2014-T6 aluminum rods CD and EF having a
diameter of 20 mm, an A992 steel rod AB having a diameter of 30 mm, and a rigid
member G. If the supports at A, D, and F are rigid, determine the average normal
stress developed in rods AB, CD, and EF.
4-54. The assembly consists of two 2014-T6 aluminum rods CD and EF having a
diameter of 20 mm, an A992 steel rod AB having a diameter of 30 mm, and a rigid
member G. If the supports at A, D, and F each have a stiffness of k = 300 MN/m,
determine the average normal stress developed in the rods when the load is
applied.
