3. Obtain the membrane stress resultants for the axisymmetric shell whose cross- section is shown in Figure Q3. The shell is composed of a hemisphere and a circular cylinder and only vertical displacement is restrained at the base. The shell has a self weight of y per unit area and is subjected to an internal pressure P. Express your solutions in terms of and y. Sketch the distribution of the meridional resultant for the case R = 5m, L= 10m, y = 200Kg/m and P = 100 kN/m. Cy
