hi many thanks ill give this one a watch when i get home from work.

Hello All I have recently been trying to get my head around torque and think I am getting there. but I am struggling to understand the different of using a wrench to move an object i.e a bolt and using a belt to move something ok i.e an alternator. I don't get is it the entire lenth of...
