Question

The lead of a screw is the distance that the screw advances in a straight line when the screw is turned 1 complete turn. If a screw is 2 1/2 inches long and has a lead of 1/8 inch, how many complete turns would get it?

Answer 1

Answer:

It would get 20 complete turns.

Step-by-step explanation:

Given:

The lead of a screw is the distance that the screw advances in a straight line when the screw is turned 1 complete turn. If a screw is 2 1/2 inches long and has a lead of 1/8 inch,

Now, to find complete turns.

Length of screw = $2\frac{1}{2}=\frac{5}{2}=2.5\ inch$

Lead of screw = $\frac{1}{8} =0.125\ inch.$

As, given the screw advances in a straight line when the screw is turned 1 complete turn.

Now, to get the number of complete turns it would divide length of screw by lead of screw:

$2.5\div 0.125\\\\=\frac{2.5}{0.125}\\\\=20.$

Therefore, it would get 20 complete turns.
