am reading God’s Philosophers: How the Medieval World Laid the Foundations of Modern Science by James Hannam which describes the designs and ideas created in medieval Europe passed down through time to today.

the whippletree was a contraption used to distribute the point load drawn by several draught animals abreast evenly across a horizontal plane.

this concept can be found in the design of modern day windscreen wipers where the force from the arm of a wiper is distributed across its blade which is designed in a series of linkages resembling a whippletree.
