A circular steel rod AB (diameter d1=15 mm, length L1=1100 mm) has a bronze sleeve (outer diameter d2 21 mm, length L2=800 mm) shrunk onto it so that the two parts are securely bonded (see figure). Calculate the total elongation δ (mm) of the steel bar due to a temperature rise ΔT=200oC. (Material properties are as follows: for steel, Es=210 GPa and αs=12x10-6/C; for bronze, Eb=110 GPa and αb=20x10-6/C.

Dependence on mechanical properties

The mechanical properties of materials are those structures that include the reaction to the load used. Metal switching features determine the scope of the usefulness of the content and establish the expected service life. Machine structures are also used to help distinguish and identify material objects. The most common mechanical properties considered are strength, ductility, stiffness, impact resistance, and resilience to fractures.
