An aluminum container has the geometry shown in the figure (the bottom part is a rect- angular box and the top is half a cylinder). The outside dimensions are shown. The wall thick- ness of the bottom and all the vertical walls is 2t, and the walls thickness of the cylindrical section is t. Determine t if the tank weight is 30 lb. The specific weight of aluminum is 0.101 lb/ n. 10 in 1n. 24 in. 12 in
