Feel it I feel it
I feel it

I know what to do
When I'm about to poop
I go to the potty
Pull my underwear down
Then I sit & wait
Sit & wait
Sit & wait till the poop plops down

Then I wipe & wipe
Till brown leaves town
Put it in the potty & flush it down
Bye, bye poop
Bye bye poop

Then I pull up my pants
Wash my hands
Wash my hands &
Do the potty dance

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
