A pipe with oil pressure of 3000 psi is closed by a valve so that the water is not flowing. Given a pipe inside diameter of 3 inches and a wall thickness of 0.25 inches,a). Determine the state of stresses in the walls and indicate these stresses (including arrows to denote the direction of the stresses) on the element below.b). Then, determine the maximum in-plane shear stress on the wall of the pipe using Mohr's Circle.
A steel bar is attached to a wood support beam with four 20 mm diameter lag screws. The steel bar is 75-mm-wide by 6-mm-thick. For the steel bar, the yield strength is 260 MPa and the ultimate bearing strength is 350 MPa.
What are two or three quality management tools used in data collection? What types of quality management tools do you utilize to make personal or business decisions? How do you use these tools in the decision-making process?
A 45 kg machine is placed at the end of a 1.6 m long cantilever beam of elastic modulus 200 x 109 N/m and cross-sectional moment of inertia 1.6 x 10-5 m4.
A direct shear test is performed on a saturated specimen of loose sand. A normal stress equal to 100 kPa is applied and a maximum shear stress of 75 kPa is measured in the shear test. Determine the principal stresses and the orientation of these p..
