2.4 (A). A 75 mm diameter compound bar is constructed by shrinking a circular brass bush onto the outside of a
50 mm diameter solid steel rod. If the compound bar is then subjected to an axial compressive load of 160 kN
determine the load carried by the steel rod and the brass bush and the compressive stress set up in each material.
For steel, E 210 GN/m²; for brass, E = 100 GN/m². [I. Struct. E.] [100.3, 59.7 kN; 51.1, 24.3 MN/m².]
