A yoke in its simplest form...
Illustration
Object:
A yoke in its simplest form is a long pole that you balance horizontally behind your neck. It stretches out for a foot or two past each shoulder. Fancier versions have a cut-out spot for your neck and are contoured to fit comfortably over your shoulders. From the ends of the pole hang hooks for buckets or bags. A yoke not only frees up your hands while you are carrying a heavy load, but it also makes you able to bear much more weight than you otherwise could.
