2. A sheet metal whose Poisson's ratio is 0.29, coefficient of thermal expansion is 10 ×10-6 /°C, E = 100 GPa, with the thickness of 5 mm, width 0.6 m and length 3 m is being stretched uniformly by a force of 240000 N along its width. Its initial temperature is 360°C and after the process is finished, the temperature is cooled down to 280°C, determine the percentage volume change of the sheet from the initial, unstressed state. 3 m 0.6 m -240000 N

14. A commonly used method of fastening one part to another part iscalled “shrink fi tting.” A steel rod has a diameter of 2.0026 cm, and afl at plate contains a hole whose diameter is 2.0000 cm. The rod is cooledso that it just fi ts into the hole. When the rod warms up, the enormousthermal stress exerted by the plate holds the rod securely to the plate. Byhow many Celsius degrees should the rod be cooled?
