How does Solidworks input loads? I am trying to create an elliptical loading on a solid but am not exactly sure what to input as my initial loading. I have the elliptical equation inputted into the non uniform section of the force settings. Basically the maximum loading at the root will be about 1800 lbf and then decrease elliptically to 0 at the tip. What should I input in the force box when creating a new force? Do I input 1800? or do I input the total load over the entire span of the wing? So say I need 24000 lbs of lifting force, would I input that?
