Unformatted text preview: with the longitudinal axis. The maximum internal pressure is 800 kPa, and the inside radius is 2.0 m with a wall thickness of t = 10 mm. Problem 3 a) Find σ θθ and σ zz b) Determine the maximum shear stress, as well as the normal stress and the shear stress acting on the weld. c) Use the von Mises and Tresca criteria to determine at what internal pressure the vessel yields ( σ y = 50 ksi). Comment. Is one of the criteria more conservative than the other? Forces (F1, F2 and F3) are applied to the faces of a rectangular block of material, as shown below. The dimensions of the block are x 1 = 15 cm, x 2 =9 cm and x 3 =3 cm. Calculate the fractional change in x 1 due to the resulting elastic deformation. The Young's modulus is 225 GPa; the Poisson's ratio ν is 0.33 Problem 4 (F 1 = 70 kN, F 2 = 25 kN, F 3 = 45 kN)...
