A load P is supported by a structure
consisting of rigid bar ABC, two identical solid
bronze [E = 16300 ksi] rods, and a solid
steel [E = 30200 ksi] rod, as shown. The
bronze rods (1) each have a diameter of 0.7 in. and they
are symmetrically positioned relative to the center rod (2) and the
applied load P. Steel rod (2) has a diameter
of 0.49 in. Assume L1=36 in
and L2=67 in. If all bars are
unstressed before the load P is applied,
determine the normal stresses in bronze rods (1) and steel rod (2)
after a load of P = 34 kips is
applied.
