Show the complete solution An anchor chain is wound around a drum with radius 1.5 ft.If the Drum is rotated through an angle of 250° how far will the anchor be lowered?

Answer 1

Solution:

The length to which the anchor be lowered is equal to the arc length of rotation on drum.

Arc length$=\dfrac{\theta}{360\degree}\times 2\pi r$

$=\dfrac{250\degree}{360\degree}\times 2\times\dfrac{22}7\times 1.5 \\\approx6.55\ ft$
