If the mine winch drum diameter is 6m calculate how far the counterweight will lift for each single rotation of the drum use the formula c=2ttr

To calculate how far the counterweight will lift for each single rotation of the drum, we can use the circumference formula, which states that the circumference (c) of a circle is equal to 2 times pi (π) times the radius (r) of the circle.

Given that the drum diameter is 6m, we can determine the radius by dividing the diameter by 2:
Radius (r) = Diameter / 2 = 6m / 2 = 3m

Now we can calculate the circumference (c) using the formula:
c = 2πr

Plugging in the value of the radius, we get:
c = 2π(3m)

Now we can calculate the circumference:
c = 6πm

Therefore, for each single rotation of the drum, the counterweight will lift a distance equal to the circumference, which is 6πm (approximately 18.85m).
