A thin-walled pressure vessel is constructed by bending a 0.5 cm thick plate into a cylindrical shape. A curved plate is bolted over the gap as shown. The 1 cm diameter bolts are spaced 3 cm apart. The bolt metal shear strength is 30 MPa. What pressure can the vessel hold before the bolts shear? Assume no bending and no stress concentration at connections. 3 cm 3 cnm t-0.5 cm Oa. 196 kPa Ob. 523 kPa °C, 250 kPa Od. 784 kPa Oe. 393 kPa r-20 cmBols, D-1 cm
