13. A strain gage is mounted to the outer surface of a thin-walled boiler as shown in Fig. 13. The boiler has an inside diameter of 60.6 in and a wall thickness of 1.060 in, and it is made of stainless steel [E = 28,000 ksi; v = 0.27]. Determine: (a) the internal pressure in the boiler when the strain gage reads 120 µe. (b) the maximum shear strain in the plane of the boiler wall. (c) the absolute maximum shear strain on the outer surface of the boiler. Fig. 13
