1. Given:
a) The material is 2024-T4 aluminum with a yield
strength of 47 ksi
b) The rod length L=6 in and arm a=8 in
c) The rod outside diameter d=1.5 in
wall
rod
d) Load F=1000 lb
2. Assumptions:
a) The load is static and the assembly is at room
arm
temperature
b) Consider shear due to transverse loading as well
F
as other stresses
a
3. Problem:
a) Determine the safety factors for the bracket rod shown in figure based on stress elements at A and
B points by using:
The maximum shear theory (MSST)
The distortion-energy theory (DET)
And compare them
b) Plot the failure diagrams in the oa, O3 plane to scale and locate the coordinates of the stress state
c) Estimate the factors of safety from the two theories by graphical measurements along the load line
