Thnx Schrodinger's hat , for ur time. u guys r quicker than i was expecting. u explained on my question very well. But i want to clear this thing with a little more simplification.
the torque & HP value i mentioned are about yamaha FZ motorcycle (loaded with single cylinder, 2 valve, HOTC).
Q. suppose i put a lot of weight (quite much like 100-500 Kg) on the engine fitted in a vehicle (not particularly this bike, but in general, any engine however designed) then which component (torque or Horse Power) will b responsible in engine by which it will rotate the wheel. & similarly in an other case which component (torque or Horse Power) will b responsible in engine by which it can pull heavily loaded cart with great speed (like in case of railway train). If my question is clear to u , then please clearify it, & if not , then tell me. I'll try to make it more clear.
Thnx
Also Thnx to Daniljel Gorupec & lemur or their precious time to this post
I also want a thorough detail on gearbox & gear ratio, but after understanding torque & HP completely
