Problem #2: A steel bolt with a diameter of 8 mm fits through an aluminum sleeve with and outer diameter d. = 13 mm and an inner diameter d; = 10 mm. The apparatus is snug-fit and stress-free at an initial temperature of 20° C. If the apparatus is slowly heated to 110° C, find the axial stress in the bolt and the sleeve, and state whether each is in tension or compression. You may ignore the thickness of the washers at either end of the sleeve. Aluminum Steel 200 14x10-6 Young's Modulus (GPa) 70 Coeff. Thermal Exp. (/°C) | 23×10-6

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.
