A 100-mm-diameter cast Iron shaft is acted upon by a 10 kN. m bending moment, a 8 kN. m torque, and a 150 kN axial force simultaneously.

Air at 1 atm enters a thin-walled (5-mm diameter) long tube (2 m) at an inlet temperature of 100°C. A constant heat flux is applied to the air from the tube surface. The air mass flow rate is 140 * 10-6 kg/s.

The unit cost of natural gas ($/ft3) for residential customers is generally lower than that for the electric power industry. a) - True b) - False

The Reynolds number, rhoVD/μ is a very important parameter in fluid mechanics. Determine its value for ethyl alcohol flowing at a velocity of 4 m/s through a 2-in.-diameter pipe.

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.
