WebJul 11, 2024 · As you understand, with the increasing friction coefficient, the wall shear stress increases. Also with the increasing viscosity of the fluid, it increases. Furthermore, it increases exponentially with the increasing velocity of the fluid. WebThe maximum shear stress created in a solid round bar subject to impact is given by the equation: where U = change in kinetic energy; G = shear modulus; V = volume of rod; and U = Urotating + Uapplied; Urotating = 1 2 Iω2; Uapplied = Tθdisplaced; I = mass moment of inertia; ω = angular speed.
