A control rod made of yellow brass must not stretch more than 18 in. when the tension in the wire is 800 lb. Knowing that E = 15 × 106 psi and that the maximum allowable normal stress is 32 ksi, determine (a) the smallest diameter rod that should be used, (by) the corresponding maximum length of the rod.
