The inner radius of the pressurized cylindrical tank is 1.25 m and the wall thickness is 15 mm. It is made of steel plates welded along the seam açılı θ = 60 angles. If the pressure vessel is subjected to an internal pressure of P = 10 MPa, find the normal and shear stress components along this seam. Also, calculate the principal stresses for the given loading condition.

In the figure, both ends of the rectangular plate are under the effect of a force p = 150kN. What is the value of the shear stress occurring in the NN 'plane which makes an angle Q = 30 ° as shown in the figure? cross-sectional area is 100mm ^ 2.

Problem 4.1

The stresses shown act at a point in a stressed body. Normal and shear stress magnitudes acting on horizontal and vertical planes at the point are S, = 20 MPa, S, = 24 MPa, and Sy = 29 MPa. Assume ß = tan = 21.8°, a = 5, and b = 2. Using the equilibrium equation approach, determine the normal and shear stresses o (positive if tensile, negative if compressive) and z (magnitude only) at this point on the inclined plane shown. Answers: i MPa, T = i MPа.
