A steel loop ABCD of length 1.2m and 12mm diameter is placed as shown around a 22mm diameter aluminum rod AC. Cable BE and DF, each of 14mm diameter, are used to apply the load Q. Knowing that the ultimate strength of the steel used for the loop and the cables is 470MPa and that the ultimate strength of the aluminum used for the rod is 270MPa, determine the largest load Q (allowable) that can be applied if an overall factor of safety of 3.02 is desired.

A steel loop ABCD of length 1.2m and 12mm diameter is placed as shown
around a 22mm diameter aluminum rod AC. Cable BE and DF, each of 14mm
diameter, are used to apply the load Q. Knowing that the ultimate strength of the
steel used for the loop and the cables is 470MPa and that the ultimate strength of
the aluminum used for the rod is 270MPa, determine the largest load Q (allowable)
that can be applied if an overall factor of safety of 3.02 is desired.
