A plate girder cross section consists of two flanges, 1 ½ inches × 15 inches, and a 5/16-inch × 66-inch web. A572 Grade 50 steel is used. The span length is 55 feet, the service live load is 2.0 kips/ft, and the dead load is 0.225 kips/ft, including the weight of the girder. Bearing stiffeners are placed at the ends, and intermediate stiffeners are placed at 6-2" and 12'-9" from each end. Does this girder have enough shear strength? a....
2. A piston-cylinder device maintain a constant pressure of 800 kPa while containing 20 kg of saturated water vapor. The system is heated with a resistance heater for 10 min at a current of 8 A at the standard wall voltage of 120 V. In that time, 3.2 kJ of heat is lost through the walls. What is the temperature at the heated state? 3 5-18E Hydrogen is contained in a piston-cylinder device at 14.7 psia and 15 ft. At...
