Odd question but how muc energy or force does 62kg have when it is dropped about 3 foot?
Reason I ask is I want to make a fence post knocker. There are currently two main types. One is a long arm that is raised & lowered on the tractor 3 point link in an action similar to using a hammer. The other is using a weight raised up & droped onto the post top. That type is split in two with internal & external weights.
This one is a hydrolic lifted internal weight

This one is a hydrolic lifted external weight but much longer drop

I thought that a hydrolic ram would have enough power to just push the post in directly. It would have to be fitted to a heavy item so think the back of the tractor would be better than the front. So back to the question how much energy is transfered to the post after a 3 foot drop per kg of weight.
