Hi,
This is more of an adjustment question and it may sound silly. I have a novelty clock: the pendulum rod is wire and the bob is metal. If I move the bob up or down, will it regulate the speed? I hope this is comprehensible and thanks for your help!
Regards.

Moving the bob up makes it run faster and
moving it down makes it run slower.
That is true for the most part unless the rod is
quite a bit heavier than the bob. In such a case,
moving the bob above about half way will start to make
it run slower. If the bob is heavier than the rod,
this point of inflection is closer to the fulcrum
of the pendulum.
In all cases, if the bob is more than half way down,
moving it up will speed it up and moving it down
will slow it down.
This is not always true for a pendulum that has weight
above the fulcrum.

Don't worry SBug. Scottie brings more practical experience
While I tend to think in terms of the engineering.
I don't expect that to change for either of us,
as it shouldn't.

Your always so straight forward.
Should be, "you're" as it is a contraction of the pronoun, "you" and the verb, "are" while, "your" is an adjective that describes a noun such as, "your mother", "your clock" et cetera.

Pet peeve of yours too, Scottie? It always grates on me to see "to tight" or similar misuse of "to" in place of the proper "too" as well. :)

Actually, that should be "tinker's dam"...or maybe you knew that but just misspelled it. Yoda:whistle:
Now, I'm no rouge scholar Bangster, but even I know a dam is a structure used to block the flow of water:cyclops:. Damn is an expletive like dang or darn. However, the word damn is an off shoot of damnation and was once considered profanity. How did I do Scottie:p

A tinker's dam (in case you want to know) is a structure used by plumbers in the past to keep solder contained as they flooded the joint with solder. Whatever the material used was, it was discarded after use ... having no additional value.

I have learned something today. Thanks, Shutt.

Ezzackly. Not only plumbers, but early-day pot menders called "tinkers". Possibly from "tin".

And d**n was not misspelled. It was spelled correctly but misused.
Far be it from me to argue with my American brothers, but, you guys are mistaken. In English (not American English) The phrase " I don't give a Tinker's damn" has nothing to do with plumbing. While you guys may use the term as Shutterbug has described it, for the rest of the world it is either a substitute for cursing or a phrase to describe something as worthless. The assertion that a Tinker's Damn should be spelt as Tinker's Dam is a fallacy. Well, that's my story and I'm sticking to it!

It's colloquial. Many terms and phrases have lost their original meaning and their new meaning becomes accepted - the original often forgotten.
