Which option can John use for transferring materials between machining centers and inspection centers in his factory? John needs to implement a flexible manufacturing system. He plans to do away with the fixed mechanisms in his factory that are used to transfer parts and materials and employ various BLANK
to navigate without human drivers. They will be used to transfer materials between machining centers and inspection stations.

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)
