# Making clocks

Homework Helper
You decide to start a business selling clocks.

You decide Roman numerals make a clock look a lot more stylish and that all of the clocks you sell will use Roman numerals. In the interest of efficiency, you need a single mold that will create all of the numbers necessary for your clock. Each mold set can be cut however necessary (i.e group two I's or a single I, etc), but each numeral on the clock has to be a single piece (i.e. the XI has to be next to each other on the mold set). You can use more than one mold set for each clock, but every symbol on the mold sets used have to be used. If you have extra V's, extra I's, extra X's, then you're just wasting resources.

What should be the layout of each moldset (i.e. - what Roman numerals should be on each set) and how many sets are necessary for each clock.

Oh, darn. I can't delete this and repost even immediately after posting. How did I wind up one level to high when I posted this?!:grumpy:

Not sure I understand the question, but going with my best interpretation...
I I I V I I I X laid out inside an annular region so that the X is again followed by the I I I ... If that makes no sense, I probably didn't understand the question. But if it does, that would be an 8 symbol mold, and it assumes that IV is used to represent 4. There seem to be obvious issues with such a mold (outside the parameters of the puzzle), but that may again be because I'm misunderstanding the question.

Use an acid etching machine. Have a computer print out the design and have it etched on a metal clock face.

Do I win?

Check the pictures of the clocks. This is the norm for clocks using Roman numerals. There's a reason for that norm.

I saw a remarkable clock the other day. It did not have the "normal" (Louis XIV) clock configuration. My friends, who were present when I pointed it out, did not understand my remark.

It's not easy being geek
But geek is what I am and I have to learn to live with it.

Is that why there's a IIII instead of a IV?

That is the traditional design for Roman Numeral clocks, yes.

4 X's, 4 V's, and 20 I's. Means you need 4 identical molds to make one clock.

Slice each up as necessary to make the numerals for your clock (note that X and I look identical whether they're upside down or right side up).

Boy, do I feel stupid for throwing in all those I's before the V.

Is that geeky?

Wasn't this one, was it?

I have now spent too much time on trivia ranging from the Roman spelling of Jupiter (or at least parts thereof) to the time of Lincoln's assassination.

No. It was on someone's mantle.
