Suppose you need 
7.0m
 of Grade 70 tow chain, which has a diameter of 
/38"
 and weighs 
2.16/kgm
, to tow a car. How would you calculate the mass of this much chain?

If you've got the weight, then that's the FORCE due to gravity. F=ma, so you've got the F bit. The a bit is ACCELERATION. On the earth, that's 9.8, or about 10. So, if you DIVIDE the WEIGHT by the ACCELERATION, you'll get the MASS. m =W/g. http://perendis.webs.com
