A force F of 40000 lbf is applied to rod AC the negative Y-direction. The rod is 1000 inches tall. A Force P of 25 lbf is applied in the negative Z- direction at point E, and a force R of 75 lbf is applied in the negative Z-direction at point F. Rod AC has a diameter of 1 inch from A to C, a diameter of 1.5 inches from B to C, and all fillet radii are 0.25 in. The rod is made of 1020 CD steel, and has a Sy of 135 ksi, a Sut of 150 ksi, and an εf = 0.15. Determine the factor of safety n at point B.

Explanation:
A force Fof 40000 lbf is applied to rod AC
the negative Y-direction. The rod is 1000
inches tall. A Force P of 25 lbf is applied in the
negative Z- direction at point E, and a force R
of 75 ibf is applied in the negative Z-direction
at point F. Rod AC has a diameter of 1 inch
from A to ca diameter of 15 inches from 3
tic, and all fillet radii are 0.25 in. The rod is
made of 1020 CD steel, and has a Sy of 135
ksi, a Sur of 150 ksi, and an ef = 0.15.
Determine the effective stress at point B
