a crank is a bent portion of an axle, or shaft, or an arm keyed at right angles to the end of a shaft, by which motion is imparted to or received from it.

Where as a sprocket is a profiled wheel with teeth that meshes with a chain, track or other perforated or indented material. It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth.

And what differentiates a cog from a sprocket from a gear?

Well you see latch they are all toothed wheels. Gears are designed to mesh with other gears, and the geometry of the teeth is optimized for this purpose.
Sprockets are designed to drive, or be driven by, a chain (such as in a bicycle) so its teeth are shaped for that purpose (pointier than gear teeth). A cog -- or more properly, a cogwheel -- as I understand the term, has squared-off teeth designed for a different kind of mechanism.
I hope that's right latch i just kinda winged it of the top of my head!
LOL
Okay and no more ?'s now!!!!!!
