minimum allowable diameter

1. A steel rod with a cross-sectional area of 0.25 in.2 is stretched between two fixed points. The tensile force in the rod at 70°F is 1200 lb. (a) What will be the stress at 0°F? (b) At what temperature will the stress be zero? Use α = 6:5 106/°F and E = 29×106 psi.

 

2. A steel rod is stretched between two walls. At 20°C, the tensile force in the rod is 5000 N. If the stress is not to exceed 130 MPa at 20°C, find the minimum allowable diameter of the rod. Use α = 11:7 × 10-6/°C and E = 200 GPa.
