Question

2. A cylindrical tank holding oxygen at 5000 kPa pressure has an outside diameter of

500 mm and a wall thickness of 10 mm. It has been determined that a critical point on the tank is subjected to the tensile stress of 465 MPa in x-direction, compressive stress of 350 MPa in y-direction and shearing stress of 600 MPa. By using Mohr’s Circle;

1. Sketch the plane stresses element for the critical point.
2. Determine the principal stresses and their locations.
3. Determine the maximum shearing stresses and their locations.
4. If the critical point on tank is rotated to an angle of 25° clockwise from the x-axis, determine the normal and shear stresses on the plane.
