An unpressurized vessel is lоаded by hоrizоntаl force Px = 60 N, verticаl force Py = 160 N, and torque T = 5 N·m acting in the directions shown. Determine the normal stress σy at K on the outside of the vessel.Vessel geometry height, h = 50 mm outside diameter = 50 mm inside diameter = 46 mm wall thickness = 2 mm cross sectional area = 301.59 mm2 Ix = Iz = 87,010 mm4 J = 174,020 mm4 Q = 2,305.3 mm3
An unpressurized vessel is lоаded by hоrizоntаl force Px = 90 N, verticаl force Py = 160 N, and torque T = 5 N·m acting in the directions shown. Determine the magnitude of shear stress τyz at K on the outside of the vessel.Vessel geometry height, h = 48 mm outside diameter = 48 mm inside diameter = 42 mm wall thickness = 3 mm cross sectional area = 424.12 mm2 Ix = Iz = 107,830 mm4 J = 215,660 mm4 Q = 3,042 mm3
