Answer:
20 turn
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW
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 the screw is 2 1/2 inches long and has a lead of 1/8 inch, how many complete turns would get it all the way into a piece of wood?
From the question, the screw is 2 1/2 inches long which is the LENGTH , we can convert this to Fraction, which is called an improper fraction, by multiply the denominator (2) by the whole number(2) then add to the numerator (1) all over denominator= [(2×2)+1]/2 = 5/2
The number of turn= Lenght of the screw / lead of the screw
=( 5/2inch)/(1/8inch)
= 5/2 ÷1/8
5/2×8/1
=40/2
=20
Therefore, the complete turns it would get it all the way into a piece of wood is 20 turn
