लुहार और उसकी छड़ें... (The ironsmith and his bars...)

विशेष नोट : अगर आप जवाब ढूंढ लेते हैं तो ठीक, वरना कमेंट लिख दीजिएगा, मैं जवाब आपको मेल के जरिये भेज दूंगा...

अपनी दुकान पर एक लुहार को लोहे की छड़ें तोलनी हैं, जिनका वज़न एक से लेकर 3280 किलोग्राम तक है... वह ग्राम के हिसाब से कोई छड़ नहीं बेचता... उसे दो पलड़ों वाली अपनी तराजू पर कोई भी वज़न तोलने के लिए कम से कम कितने बाटों की ज़रूरत होगी, और वे कितने-कितने वज़न के होने चाहिए...?

Now, the same riddle in English...

Special Note: If you succeed in solving this one, well and good; but in case, you don't, just leave a comment, and I will mail the answer to you...

An ironsmith, in his shop daily, had to weigh the ironbars from 1 kg to 3280 kgs... He doesn't sell anything in grams... What are the minimum number of different weights required and how heavy should they be...?
