The accent problem of two-syllabled-words

The rule applies quite widely.  There are a lot of verb-noun pairs with this property.
What's frustrating, however, is that the pattern does not apply universally! 

I think you mean consent.  Stress the second syllable whether verb or noun.

The words listed below have the property you're talking about, Maple.  Compared to the thousands of verbs in the English language, there really aren't that many.  Yet, when faced with the list, it is a lot of words to learn!  This is not an exhaustive list.  Maybe others can add to it.

Stress the first syllable for the noun form (and use the final s where indicated).  A few are not nouns but adjectives, as marked.  Stress the final syllable for the verb form.

The meanings of the two are often similar, but there are quite a few where the noun and verb pair give two words only slightly related, or not at all.  For example, you contract' a disease, and you sign a con'tract.
