a. figure 1 shows a large pressure vessel fabricated by welding together steel plates of 12 mm thickness as shown. If the stress acting normal to the welds must be less than 80 MPa, what is the largest allowable internal pressure? b. determine the state of strain in the tank when the internal pressure is 0.3 MPa. The elastic modulus (?) of the steel is 200 GPa, and the Poisson’s ratio (?) is 0.3. c. The welded joints are to be replaced with equally spaced rivets (loaded in single shear), each with a diameter of 10 mm and maximum allowable stress of 80 MPa. For an internal pressure of 0.3 MPa inside the tank, determine: (i) The minimum rivet spacing (?) along the circumference of the tank. (ii) The minimum rivet spacing (?) along the height of the tank. d. If the pressure vessel is subjected to a temperature change of 50°C determine the change in height. The co-efficient of thermal expansion for steel can be taken as ? = 11.2 × 10−6 °C−1.
