Question
Steam at 320°C flows in a stainless steel pipe ( k=15Wm-K whose inner and outer diameters are 5 cm and 5.5 cm , respectively. The pipe is covered with 3-cm-thick glass wool insulation ( k=0.038Wm*K ). Heat is lost to the surroundings at 55°C by natural convection and radiation, with a combined natural convection and radiation ...

Question
A typical aluminum-alloy scuba diving tank is shown. The outside diameter of the tank is 200 mm and the wall thickness is 12 mm. If the air in the tank is pressurized to 20 MPa, determine: (a) the longitudinal and hoop stresses in the wall of the tank. (b) the maximum shear stress in the plane of the cylinder wall. (c) the absolute maximum shear stress on the outer surface of the cylinder wall.

Question
The structural steel column shown in figure below is fixed at its base and free at its upper end. At the top of the column, a load P = (15 + 0.05R) kip is applied to the stiffened seat support at an eccentricity of e = 9in from the cross-sectional x-axis of the I-section shape. Analyze using the AISC equations and allowable stress method to determine whether the column is safe under the applied eccentric load. Assume E = 29000 ksi and sigma_{y} = 36ksi The area of cross-section A = 10.45i * n ^ 2 the moments of inertia I = 122.671 in and 1=42.692in of the I-section.
