A pneumatic bag with tickness t is placed under a base supporting a column during a rescue operation after an earthquake. The base has a diameter of 300 mm. The load applied to the base is 34335 N and the pressure inside the bag is 42.67 psi. If the angle of the membrane bag at the perimeter of the base is 60° with respect to the vertical, determine the stress state in the plane of the largest diameter.
