## Homework Statement

I have already completed both problems. I have the same answer for both of them. I was wondering if that is possible? Are the two point loads equivalent to the distributed load?

In summary, the person completed both problems and got the same answer for both. They were wondering if this was possible and if the two point loads were equivalent to the distributed load. The stiffness matrix was used on each element, with the assumption that the middle section is perfectly rigid. This assumption simplifies the stiffness matrix and results in the same answer. They also mention using three beam elements and assuming fixed ends and zero angular displacement at the center element.

The setup is symmetric, sure.

[K][displacements] = [F]

[K] [v2;theta2;v3;theta3]=[ql/2;0;ql/2;0]

where

ql/2 = -1000
