A cylindrical vessel is pressurized to 1.7 MPa. The structure on which the vessel rests becomes damaged, resulting in uneven support that causes a twisting moment T0 of 8 106 N-m on the vessel. The vessel has an outer diameter of 2.5 m and a wall thickness of 50 mm. The steel wall has a uniaxial yield strength of 600 MPa. Determine the factor of safety with respect to yielding (a) assuming a maximum shear stress yield criterion and (b) assuming a von Mises yield criterion.

The phasor technique is not valid if the frequencies of the sinusoids in the time domain are different. Part F - Use phasors to combine sinusoids The phasor technique makes it pretty easy to combine several sinusoidal functions into a single sinusoidal expression without using trigonometric identities. However, you cannot use the phasor technique in all cases. Select the expressions below for which the phasor technique cannot be used to combine the sinusoids into a single expression. a. 45 sin(2500t 50) + 20 cos(1500t +20) b. 25 cos(50t + 160) + 15 cos(50t +70) c. 100 cos(500t +40) + 50 sin(500t 120) 120 cos(500t + 60) -100 sin(10,000t +90) + 40 sin(10, 100t 80) + 80 cos(10,000t) d. 75 cos(8t+40) + 75 sin(8t+10) 75 cos(8t + 160)
