The amazing dynamic balance write up by Jerry Holway

Recommended Posts

Last week I made a awkward post about dynamic balance. After reading and schooling myself about centrifugal forces I found this very clarifying pdf from Jerry Holway with both a mathematical approach and empirical approach towards dynamic balance. If you search on this forum for the tags dynamic balance I feel very sorry for Jerry, I can imagine it gets him a lot of headaches. Therefor I think any person who tries to make a new post (like me) should instantly be forwarded to this article: https://www.google.nl/url?sa=t&source=web&rct=j&url=http://www.tiffen.com/dynamic%2520primer.pdf&ved=0ahUKEwiaqLLKutTXAhVBK8AKHTCHCT4QFgglMAA&usg=AOvVaw0XZYXuK6mEasmXF_269YDu

 

Of course in reality there are several methodes to achieve dynamic balance but ever since iam studying this article (with the help of my father who is science teacher), I start to see that every adjustment I make on my rig always leads back to this article. As a beginning operator I feel more confedent knowing what my rig does on planet earth. Thanks to Jerry for writing this great piece (even though it's tough math there is even some humor to get you through the article)

The only thing that is frustrating is knowing that there is no more - or no less - to really understanding dynamic balance. The math originally written by Ed DiGuilio's brother, Arnold, even explains co-planar sleds.... and sleds with the monitor lower than the battery!

By the way,.. One last question... Iam seeking into a small low budget option to better balance my rig. My camera is slightly to light for my provid arm so iam adding weight to the camera. But since I don't have a yoke for my Archer monitor I cannot expand my monitor horizontally, so I always end up displacing my monitor vertically on the post, or change my battery's (I have several batteries with different weights),. If I would attach a battery (just for the sake of balancing not to power something) right under the post on the bottom of my sled with a cheap adapter plate, the relative difference in weight and position between the monitor and rear battery would be smaller and thus the rig would be easier to get in balance. Since I started to add weight to the camera I had to extend the post, I could undo that with this additional weight. Iam I thinking in the right direction, or should I start researching a monitor yoke?
