Stress verification of the tail lifting lugs on tower equipment regarding the skirt base

The force exerted by the tail hook on the skirt base changes, as the equipment goes from lying horizontally to being vertical, from a vertical tensile force on the weld to a horizontal shear force. Calculus can be used to determine the changes in tension and shear force at an angle α, in order to find the maximum value.
Do experts have any calculation formulas or spreadsheets that you could give me?
Engineering applications do not require calculus; for specific guidance, one can refer to the pressure vessel design manuals or the algorithms available in Pvelite – simply divide the angles into equal parts, increasing them by 5° or 10°
It can also be solved using calculus, allowing for the rapid determination of the angle at which the axial force is greatest
