Determining max shear and bending stress
WebThe shear modulus is the proportionality constant in Equation 12.33 and is defined by the ratio of stress to strain. Shear modulus is commonly denoted by S: 12.43. Figure 12.24 An object under shear stress: Two antiparallel forces of equal magnitude are applied tangentially to opposite parallel surfaces of the object. WebThe maximum shear stress at the midpoint is equal to. τ m a x = 1.5 V A = 1.5 τ ¯. where V A = τ ¯, which is the average shear stress along the entire section. That is the only viable comparison to be made, stress to stress. …
