Interchanged displacement values? #89

Closed cmoha closed 3 years ago

cmoha commented 3 years ago

Hello and good day, Are these displacement values interchanged? i.e delta1y is swaped with delta1z.

No. SegmentsZ tracks bending about the local z axis, which produces deflection in the y axis. Similarly, SegmentsY tracks bending about the local y-axis, which produces deflection in the z axis.

Thank you. Kindly, Can yo add some tests for deflections under various load types?
