Drum brake solid mechanics derivation stress

WebAbstract A new insight into the mechanics of belt friction is given. A conceptual and methodological drawback in the presentation of the classical derivation of the force required to pull the belt over a fixed drum against the hold-force and the friction between the belt and a drum is pointed out, corrected and discussed. WebConservation of angular momentum for a continuum requires that the Cauchy stress satisfy. σji = σij. i.e. the stress tensor must be symmetric. Derivation: write down the equation for balance of angular momentum for the region V within the deformed solid. ∫Ay × T dA + ∫Vy × ρ bdV = d dt{∫Vy × ρ vdV}
