as a matter of fact, in Norse mythology, Thor is a hammer-wielding god associated with thunder, lightning, storms, oak trees, strength, the protection of mankind, and also hallowing, healing, and fertility.
Even if a character is strong, they won't be able to lift the hammer if they're not worthy. The Hulk is said to be the strongest there is, but he can't break the hammer's enchantments. Cap, however, has lifted the hammer (at least in the comics). This might be a bit of a spoiler, but I'm guessing at one point in the next movies, Cap will have to lift Mjolnir.
