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?
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\n\\\\\\approx6.55\\ ft"
