Trip Hammer by Alice.
Trip hammers were usually raised by a cam and then released to fall under the force of gravity. Historically, trip hammers were often powered by a water wheel, and are known to have been used in China as long ago as 20 AD, in Rome by the 1st century AD and in medieval Europe by the 12th century. During the Industrial Revolution the trip hammer fell out of favor and was replaced with the power hammer. My Dedda and I made one. I will bring it to school to look at.By Alice Kerse.

What interesting information Alice. I think I saw one of these Hammers being used to crush wheat in an old flour mill.
Fantastic!
Great post Alice ! There were some very clever people around 2000 or so years ago .
Alice this is really interesting. The hammer you made is fantastic and shows how cams convert circular motion into linear! Well done Alice and Adam!
