As shown, a gas storage tank is composed of half cylindrical thin shells (8m long) and hemispherical thin shells (4m inner diameter) connected together by 25mm diameter bolts of 140MPA allowable normal stress. You are asked to design the tank to contain a gas pressure of 3MPA; a. What would be the most economical thickness of the shells if the material used has an allowable stress of 240MPA? b. What would be the required number of longitudinal bolts per meter length at each side of the cylindrical shell?
