Problem 2: A pressure vessel with p = 200 psi internal pressure is subjected also to a twisting moment T = 450 kips in. The vessel has an internal diameter of 20 in and a wall thickness of 0.25 in. L a) Draw a Mohr's circle for an element on the front surface, as shown, and determine the principle stresses. b) Determine whether the in-plane maximum shear stress is equal to the absolute maximum shear stress. c) Determine the tensile yield strength of a ductile material which has a factor of safety of 5 for this loading. Use the maximum shear stress theory.

The plate has a thickness of 20 mm and the force P = 3 kN acts along the centerline of this thickness such that d = 150 mm.  A) Determine the normal stress at the bottom edge of the plate Enter negative value in the case of compression and positive value in the case of tension. B)Determine the normal stress at the top edge of the plate. Enter negative value in the case of compression and positive value in the case of tension. C)Specify the location of the neutral axis measured from the bottom edge of the plate.

Q5: Draw the Mohr's Circle of the stress element shown in figure. Find: - The stresses acting on inclined plane A-B with Y -axis. A 60 6 MPa B 6 MPa 6 MPa

A stress element is shown. The material has a yield strength of 200 MPa, an ultimate strength of 275 MPa, and a Young’s Modulus of 207 GPa.
