While their method of power generation is quite different, FEderer and Nadal are the two best examples of the straight arm forehand. During practice, Nadal's is the easiest to see, so had you even posted the right player, you would've still lost terribly.
This isn't a competition, nobody here "wins" or "loses", we're all just trying to help the OP improve his game.
Rafa and Fed have very similar forehand mechanics. I'm busy right now, I'm not going to go look for a video. I happened to have a Fed vid in mind that I remembered him hitting with a bent arm in. It's obvious Rafa would do the same thing. Do you think he'd try and force a straight arm and whiff on a shot if it's slightly too close to his body?
