Are the grammatical forms ものか and だろうか questions?

Question

For some reason, I have had the impression that か at the end of a sentence marks some kind of question that is being asked. However, in these examples from 日本語総まとめ　文法:

うれしいもんですか。困っているんです。

(I'm not at all pleased. I am not in a good situation.)

デジカメが壊れた。なんとか直らないものだろうか。

(My digital camera is not working. I wish I knew how to fix the problem.)

It appears to not be an adequate or translation of the grammatical forms. The first example doesn't seem to explain the existence of any question (if one exists). The second one might be better translated as:

"My digital camera is broken. I wonder if something cannot be done to fix it."

I thought this conveys the idea of something being questionable. How would the first example be better explained/translated so that whatever is questionable is not lost?

Answer 1

The first one is a rhetorical question.

Would I be pleased at all (in this situation)?
Implication: I am not pleased.

The second one is a question unto oneself.

Wouldn't there be some way for it to get fixed?

Answer 2

In the second example, the grammatical form is the ない form of a verb followed by ものか or だろうか. It indicates a desire for, or hope of, something.

So I think the example translation is more accurate because it shows the speaker's wish that it can be fixed.

A couple more examples:

世界中が平和になる日が来ないものだろうか。

いつも原田{はらだ}選手に負けている。何とかして勝てないものか、作戦を考えているところだ。
