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.
A steel scuba tank is 24 in. long and has an external diameter of 7.25 in. and an internal diameter of 6.7 5in. Say the tank is to carry a pressure of 3000psi . Determine the hoop stress in the tank wall. Determine the axial stress in the tank wal..
the pressure ratio across the compressor is 9 and the maximum temperature is 827c.the turbine and comprssor processes are adiabatic with turbine efficiency of 90% and a compressor efficiency of 85%.
Determine (5) the maximum shear stress at failure Tao,max and (6) the angle of the plane on which Tao,max acts; calculate (7) the available shear stress on the plane.
An ocean outfall diffuser that discharges treated wastewater into the Pacific Ocean is 500m from a public beach. The wastewater contains 105 coliform bacteria per milliliter. The wastewater discharge flow rate is 0.3 m3/s.
Determine the vertical deflection in inches at the midpoint, called point F, between points B and C. Use E=29,000 Ksi, I=800 inches^4, and A=6.0 inches^2 for all members. Use the Virtual Work Method.
A load of 14 tonnes is suspended at the end of a steel rope.If the load is subjected to a maximum acceleration/deceleration of2.5m/s2, when raised and lowered, calculate the diameter of therope needed to support the load.
