The deviation of a first point on the elastic curve of a beam measured perpendicular to the original position of the beam, from the tangent drawn to the same curve from a second point is equal to:
1
Square of the moment of the area of the moment diagram between the above two points about the first point divided by El of beam
2
Moment of the area of the moment diagram between the above two points about the first point divided by El of beam
3
Square of the area of the moment diagram between the two points divided by the El of beam
4
Area of the moment diagram between the two points divided by the EI of beam
