AC has an outside diameter of 250mm and CD has an outside diameter of 150mm. Both pipes have a wall thickness of 8mm. Find the torque T if the allowable rotation between A and D is 2.5°. Gsteel= 77.2GPa, Gcopper = 44GPa. Hint: Use statics to find the torque in each segment.

Which of the following is an easy way to remember the modified “x” tire rotation? a. nondrive wheels straight, cross the drive wheels b. drive wheels straight, cross the nondrive wheels c. drive wheels crossed, nondrive wheels straight d. drive wheels crossed, nondrive wheels crossed

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
