i think "uğraşmak" has a more stronger meaning than "to try".

i used to use it when i first started learning turkish, but i was told that it is better to use "çalışmak" or "denemek" for "to try".

but i could be wrong though

Çalışmaya çalışıyorum...
I am trying to study/I am trying to work.

It is not hard to understand which is the meaning of çalışmak in a sentence.. "work" or "study" or "try".

"uğraşmak" means the same thing for that like you said, and also gezbelle is right too. Generally "uğraşmak" refers on something for harder.

The meaning of "to try" is used with a verb. So you can understand that the main verb is "to try" and the other is theaction to try.

Problemi çözmeye çalışıyorum.
I am trying to resolve the problem.

Ahmet'e ulaşmaya çalışıyorum.
I am trying to reach Ahmet.

Underlined wordgroups are the actions whch you try to do.

By the way, the meaning of "to study" is a little different. It is not directly "to study". It is "to study yourself". If you are in school and teacher teachs you something, that is not "çalışmak". But if you are studying alone or just one of your friend helps you for your study, that is "çalışmak".

Dün konuya çalışamadım çünkü elektrikler gitti, öğretmenim...
Yesterday, I couldn't study the topic because the electricity went, my teacher...

Komşular çok gürültü ediyor, çalışamıyorum.
Neighbours make a lot of moise, I cant study.

The other meanings are probably "to work". They are maybe about the place to work:

Bankada çalışıyorum
I work for a bank/in a bank.

Ankara'da çalışıyoruz
We work in Ankara.

I hope it is helpful.
Kolay gelsin

Çok geç oldu

İs it,

He was late,or it became very late ?

And if i want to say,´its getting late´ would it be,

Çok geç oluyor

I think "Çok geç oldu"="it became very late"

and "its getting late"="geç oluyor"
