Design a compound shaft attached to rigid support using bronze with G=35 GPa and allowable shear stress of 60 MPa, and Steel with G = 200 GPa and allowable shear stress of 80 MPa. Assume different values of diameter for Bronze and Steel. Compute for the ratio of the length of Steel to the length of Bronze   so that each material will be stressed to its maximum permissible limit. Give the reaction at the supports, maximum torque carried by each material, and the maximum angle of twist.

Temperature related material properties

Temperature-related properties of materials are the properties that change or show any variation with temperature variations. Various properties of materials include physical properties, mechanical properties, chemical properties, electrical properties, magnetic properties, etc. The chemical, electrical, and magnetic properties of materials are important, but the physical and mechanical properties are more important. Based on their composition and chemical bonding, materials are classified as metals, ceramics, polymers, and composites.
