Thankyou friends for your valuable suggestions.

I have one more query in using the multi load case design option for spring hanger, (i.e.) there are 13 options available out of which first nine options are defined as operating case 1, 2 .... 9, and the remaining cases are max. load, max. travel, avg. load and travel and max. load and travel.

From these, i dont understand the first nine load cases, that is operating case 1 till 9. Why these are available and when to use? Since we can select only one option in the multi load case option, if we select the operating case, say # 2, then the spring is designed for that case alone. So instead of using the multi load case option, why dont we directly enter the load case in the overall static load case option.

Please clarify....
