Problem description: The cantilever beam shown is subjected
to uniformly distributed loading ly, lz per unit length and the
end force Fx, Fy, Fz. Calculate deflection and stresses for two
load cases: i) the in-plane problem using ly, Fx, Fy only
and ii) the complete three-dimensional loading ly, lz, Fx,
Fy, Fz.
ly=-100 lz=200 unit: N/m
Fx=20000 Fy=-20 Fz=10 unit: N
Solution: The end force Fx, Fy, Fz is directly
assigned to node 5 as a concentrated (nodal) force. The distributed
loading is replaced with the equivalent body force as
