if the mine winch drum diameter is 6m calculate how far the counterweight will lift for each single rotation of the drum use a formula c-2ttr
oh no, not the ol' mine shaft question again, must have seen that at least 10 times in the last month.
C = 2πr, you have all the numbers
= 2(π)(3) = 6π m
evaluate if you have to, everybody has a calculator, if not google it
