The secant stiffness of the load, P e , can be used to calculate the initial lateral stiffness, k 0 , and point C is the yield point. The form of the relation between shear stress and rate of strain depends on a fluid, and most common fluids obey Newton's law of viscosity, which states that the shear stress is proportional to the strain rate: = d dt . The maximum/minimum values of moment occur where the shear line crosses zero. The value of the maximum shear stress is dependent on the values of normal stresses. moment of this area dA about the neutral axis between limits y, Let us see the following figure, From this formula, the maximum shear stress of a rectangular beam can be written as shown: An error occurred trying to load this video.
