The copper is included to enhance adhesion of the rubber tire casing to the wire. [a] What are ways in which the tire can fail [a preview of what to expect in EMA 4714]. *********************************************************************** Tire is basically a donut shaped pressure vessel. When the material from which the pressure vessel fails due to exceeding its failure strength, the tire fails. Thus [1] deterioration of the polymer, [2] failure of that component which sustains the majority of the applied stress are factors . [b] How might corrosion contribute to tire failure? *********************************************************************** [1] Reduction in cross-sectional area of the wire making up the steel “belts” will increase the stress applied to the remaining cross-section, eventually leading to
