3. A steel rod of 3 cm diameter and 5 m length is connected to two grips and the rod is held at a temperature of 95 °C. Determine the stress in the rod, and the force in the rod if the temperature drops to 30 °C for the following cases a. The grip ends do not yield b. The grip ends yield by 0.12 cm Assume the Young's Modulus of the rod is E = 2×105 MPa, and the CTE is a=12×106/ °C
