exceed 126 MPa and the maximum change in length of BD must
not exceed 0.001 times the length of ABC, determine the smallest-
diameter rod that can be used for member BD.
2.14 The 4-mm-diameter cable BC is made of a steel with $E$ =
200 GPa. Knowing that the maximum stress in the cable must
not exceed 190 MPa and that the elongation of the cable must
not exceed 6 mm, find the maximum load $P$ that can be applied
as shown.
