Ahollow round cylindrical steel shaft sealed on both ends has an allowable shear stress of = 120 and transmits 200 n-m of torque. the cylinder is pressurized to 2.0 mpa. it rotates at 60 rpm. hint: neglect section 3-15 in your text.

a. if the inside diameter is 90% of the outside diameter, what is the outer and inner diameters? use preferred sizes for both. hint: neglect section 3-15 in your text. (4 points). assume a thin walled pressure vessel.

b. what is the shear stress on the inside diameter? (3 points). hint: neglect section 3-15 in your text.

c. what is the actual design factor (factor of safety) for the cylinder based upon the actual geometry (preferred sizes) of the cylinder?

d. how much power will be transmitted? (1 point)
