Recall there is a constraint equation connecting the y-displacement of sets Tip-a and Tip-b, where the degree of freedom for set Tip-a is eliminated from the system equations. Thus, apply the load as a concentrated force of magnitude –10000 to set Tip-b. Name the load Tip load. Because of the constraint, the load will be carried equally by both trusses. The crane is attached firmly to the parent structure. Create an encastre boundary condition named Fixed end, and apply it to set Attach. | |||||||
