The input distance of a screw is equal to the circumference of the screw multiplied by the number of times it is turned. If a screw with a circumference of 15mm is turned 5 times, so
that it penetrates into a piece of wood a distance of 10mm (output distance), what is the
screw's mechanical advantage?

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
